During the process of mitosis, a eukaryotic cell endures a division which is very accurate and precise which results in a formation of two genetically identicall cells. Metapahse; anaphase; telophase.
<h3><u>Answer;</u></h3>
Alpine skypilots evolve large flowers above the timberline and small flowers below the timberline.
<h3><u>Explanation;</u></h3>
- <em><u>Natural selection occurs when organisms or species with certain genotypes are more likely to survive and reproduce, compared to individuals with other genotypes, and thus to pass on their alleles to the next generation.</u></em>
- Alpine skypilots evolve large flowers above the timberline and small flowers below the timberline. This is an example of disruptive selection, which increases genetic variation.
- Longer tails in dragonflies and finches for a particular beak size are examples of directional selection, which decreases genetic variation.
- Natural selection against heavy and light field mice is an example of stabilizing selection, which reduces genetic variation
Answer:
The following punnet square would be constructed from the above mentioned cross:
b b
B Bb Bb
B Bb Bb
A punnet square can be described as a diagram which is made to illustrate the outcomes of a cross.
The results from the above punnet square show that the offsprings produced from a cross between homozygous blue and brown parent, will all have blue feathers but they all will be heterozygous for the trait.
