Answer: IA
Explanation: The allele IA has dominance over the allele I because the allele IA is a dominant trait
The frequency of allele is illustrated as the ratio of that specific allele in the population. As one knows that as the humans are diploid, so the total number of alleles is double of the total number of people in the population.
In order to determne the allele frequencies for A and B, there is a need to know that the persons with type A blood are homozygous AA, the persons with type AB blood are heterozygous AB, and the persons with type B blood are homozygous BB.
The frequency of A is:
2*(number of AA) + (number of AB) divided by 2 * (total number of individuals)
Therefore,
{2 * (200) + (75)} / 2 (200 +75 +25)
This comes out to be 475/600 = 0.792. Thus, p = 0.792.
Since, q is 1 - p
Then, q = 1 - 0.792 i.e 0.208.
Organelles are the organs of the cells , they carry out different functions.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.
