There are basically four more phases that occur during meiosis than during mitosis. The four phases of meiosis are <span>Prophase. metaphase, anaphase and telophase. In case of mitosis, you can say that there is just a single phase. I hope that this is the answer that has actually come to your desired help.</span>
This can be solved either by using a Punnet Square or you can use the formula (n(n+1))/2, where n is the number of alleles. However, using either method will give you the number of possible genotypes regardless if it's homozygous or heterozygous. If we use the second formula, that will give you 10 possible genotypes. Since you only want to know the number of heterozygous genotypes, you should subtract the number of possible homozygous genotypes. In this case, there are four. That is (A1,A1), (A2,A2), (A3,A3), and (A4,A4). Knowing this, you'd be able to figure out that there are six heterozygous genotypes.
(A1,A2), (A2,A3), (A3,A4), (A1,A4), (A1,A3), (A2,A4)
Answer:
RR x rr / Rr x RR
Explanation:
For all of the first final generation to all produce round peas, it means the parents crossed were pure breeds of both dominant and recessive genotype or one of the the parents is an heterozygote and the other is a pure breed dominant. The resulting peas will have a phenotype which is the observed round shape but their genotype may be either the homozygous RR or the heterozygous Rr.
Answer:
polar climate zone
Explanation:
the equator of the earth is the area where most of the suns rays hit the surface area. as you move towards the poles, areas receive less sunlight. the top of the poles receive the least solar radiation and are the coldest places on earth, hence the climate zone name polar.
