Two distinct genes assort independently during gamete production, according to Mendel's law of independent assortment.
One needs to perform a dihybrid cross to come to this conclusion. This implies that two genes controlling two distinct features must be examined simultaneously.
1) Beginning with the paternal generation of a cross between two pure lines, one with green and wrinkled seeds and the other with yellow and round seeds, both of which are homozygous for both genes (yyrr). The F1 will have homogenous phenotypes (round and yellow) and heterozygous genotypes (YyRr).
2) To establish the phenotypic ratio of the F2 if the F1 individuals are crossed, a Punnett Square must be performed.
The F1 individuals will generate their various gametes with the same likelihood if the genes assort separately. There will be a 1/4 fraction of each potential gamete: YR, YR, yR, yr.

Consequently, it is accurate to say that the pattern underlying evolution is supported by scientific data.
What's evolution in biology?Evolution is the change in the heritable characteristics of biological populations over time. Evolutionary processes provide diversity at every degree of biological complexity. The final common ancestor of any and all life on Earth is the last universal ancestor. Changes in an organism's heritable characteristics, or genetic makeup, are how organisms evolve. For instance, a person may get the "brown-eye phenotype" from one of their parents because eye color is a heritable trait for humans.
Who discovered evolution?It's general knowledge that Charles Darwin is credited with "discovering" evolution. However, the historical record reveals that between 1748 and 1859, the year when Darwin published Just on Origin of Species, around 70 distinct authors wrote works on the subject of evolution.
Direct evidence of evolution: The emergence of antibiotic-resistant bacteria

c. hypertonic right temporalis
d. hypertonic left lateral pterygoid
While opening the mandible moves/gets pulled to the right instead of depressing in a straight line. Hypertonic Right Lateral Pterygoid is LEAST likely.
The craniomandibular muscle known as the lateral pterygoid performs a significant role in the inferior temporal area. It is active during chewing and mandibular motions like protrusion (moving the jaw forward), abduction (moving the mandible downward), and mediotrusion (mandibular condyle movement towards the midline). It functions best when speaking, singing, and clenching.
There are two heads or bellies on the lateral pterygoid muscle. In comparison to the superior belly, the inferior belly is three times bigger. It is the only masticatory muscle with fibres oriented horizontally among all the masticatory muscles.
With the help of the mylohyoid muscle and the anterior belly of the digastric muscle, the lateral pterygoid muscle depresses the jaw and opens the mouth.

B. a monohybrid cross
C. an impossible cross
D. a dihybrid cross
A genetic cross of a parent who has a dominant phenotype, but an unknown genotype (R?,Y?), with a parent who contains only recessive alleles (rr yy) is known as a testcross.
Results from this type of cross show whether the dominant parent was homozygous or heterozygous for the dominant allele.
In a diploid organism, two alleles for a particular gene are expressed and interact to produce physical traits. A species' observable characteristics are referred to as its phenotype. The genotype is the genetic composition of an organism, which includes both the alleles that are physically expressed and those that are not. Mendel's hybridization studies show how phenotype and genotype differ from one another. For instance, the diploid genotypes of the plants in the P, F1, and F2 generations are related to the phenotypes that Mendel observed in his crosses between pea plants with different features.
We'll use seed colour as an illustration of the second attribute Mendel studied. A single gene with two alleles controls seed colour. In contrast to the green-seed gene, the yellow-seed allele is dominant. All of the F1 hybrid progeny had yellow seeds when true-breeding plants with one parent having yellow seeds and the other having green seeds were cross-fertilized. In other words, the yellow-seeded true-breeding parent's hybrid offspring shared the same phenotypes as it. The allele provided by the parent who planted green seeds, however, was not simply lost, as some of the F2 offspring carried it. As a result, the F1 plants have to be genetically distinct from the parent with the yellow seeds.

consider a population of an annual plant, starting out with a single adult in year 1. suppose that each adult plant generates on average 500 seeds, of which only 15 germinate and grow to adulthood in the following year (the remaining seeds die).
In this scenario, the population of the annual plant starts with just one adult in year 1.
This adult generates an average of 500 seeds, but only 15 of these seeds will germinate and grow to adulthood in the following year. This suggests that the survival rate for the seeds is quite low, with only 3% of the seeds being able to grow into adult plants. As a result, the population growth of the plant will be slow, as only a small number of seeds are able to grow into adults each year. Additionally, the population will be highly dependent on the survival rate of the seeds, as a low survival rate will limit the overall population growth.
There are several ways to improve the survival rate of seeds in this scenario:
Improve seed quality: By selecting high-quality seeds for planting, the chances of germination and growth to adulthood will be higher.Optimize planting conditions: Proper soil preparation, moisture, and temperature conditions can ensure that the seeds have the right environment to germinate and grow.Reduce seed predators: By controlling seed predators such as insects and animals, more seeds will be able to germinate and grow.Provide proper maintenance: Proper maintenance of the adult plants, such as fertilization and pest control, can increase the chances of seed production and survival.Genetic modification: By using genetic engineering to improve the genes of the plant that are associated with seed survival.Use of companion planting: By planting other plants that can repel pests and diseases that attack the annual plant, seed survival rate will be improved.Learn more about annual plant here: brainly.com/question/13449989

Prometaphase is the stage of mitosis between prophase and metaphase. The main event that takes place during metaphase is the disintegration of the nuclear membrane.
Prometaphase is an important phase during cell division. In prophase two sister chromatids are formed inside the nucleus. To bring about cell division and separation of the sister chromatids, the nuclear membrane must disintegrate. This happens during the prometaphase.
During this phase kinetochores are also produced, which are proteins that bind to the centromeres and enables in separation of sister chromatids. This stage is also known as late prophase. Here the chromosome condensation is also completed.
So the main indication of the prometaphase is that the nuclear membrane disintegrates.

Which of the following is a likely explanation for why invasive species take over communities into which they have been introduced?Iwasive species are less efficient than native species in competing for the limited resources of the environmentwaive species are not held in check by the predators and agents of disease that have always been in place for native speciesHumans carefully select which species will outcompete nuisance native speciesInvitive species have a higher productive potential than native species.Invasive species come from geographically isolated regions, so when they are introduced to regions where there is more competition, they thrive.
The explanation for why invasive species take over communities into which they have been introduced is invasive species are not held in check by the predators and agents of disease that have always been in place for native species.
Thus, the correct option is B.
Invаsive species аre non-nаtive species thаt hаve colonised а new аreа to the point of dаmаging the surrounding environment аnd аre saw аs one of the top five mаjor threаts to the ecosystem todаy. They cаn be brought into а new environment from pаthwаys such аs ships, fishing equipment or аccidentаl releаses. This is worrying for us аs invаsive species cаn dаmаge the services the ecosystems provide us with.
Invаsive species аre cаpаble of cаusing extinctions of nаtive plаnts аnd аnimаls, reducing biodiversity, competing with nаtive orgаnisms for limited resources, аnd аltering hаbitаts. Invаsive species cаn hаve impаcts on the mаrine industries, such аs growing on mаrine structures, killing or competing with mаrine аquаculture species аnd by spreаding diseаse.
