Answer:

B

Explanation:

Answer:

B

Explanation:

There is a correlation between malaria infested regions and the allele frequency of sickle cell anemia, because the non sickle cell allele frequency is decreasing faster than the sickle cell allele frequency. The S allele is being selected for during natural selection in these areas. The S allele frequency is changing far less than the A allele frequency. This shows that the A allele is being selected against, therefore, there are far fewer of those alleles being inherited in each generation compared to the S allele. This selection of the S allele coincides with the correlation that exists in malaria infested areas and sickle cell anemia.

Two true-breeding stocks of pea plants are crossed. one parent has red, axial flowers and theother has white, terminal flowers;
xxTIMURxx [149]
This is a typical case of a dihybrid cross. 
From the phenotype of the offspring, we can conclude that the gene for the red color of the flower and the gene for the axial position of the flower are dominant.
Since we know that the ratio of phenotypes in a dihybrid cross of independently inherited alleles is
9(dominant for both traits)
3(dominant for one trait, recessive for the other)
3(dominant for the second trait, recessive for the other)
1(recessive for both traits)
we can expect 3/16 of the f2 generation to be dominamt for one trait and recessive for the other (red, terminal flowers), or to be precise 190 individuals.
