Color blindness is X linked recessive disorder. X+ chromosome carry a normal allele but Xc chromosome carries defective allele. When frequency of colorblindness female (0.10), colorblind male (0.30) and heterozygous female (0.20). Random matting population, what will be frequency of carrier female?

The Galapagos finches were an important clue to Darwin's thinking about the origin of species. These finches are believed to have descended from a single ancestral species that colonized the Galapagos archipelago, America, over a short period of time. The Galapagos finches differ in their beak shape and size. Different species feed on seeds that vary in size and hardness. Which of the following is the most likely explanation for these patterns?

In a large natural population of Mimulus guttatus, one leaf was sampled from each of a large number of plants. The leaves were crushed and subjected to gel electrophoresis. The gel was then stained for a specific enzyme, X. Six different banding patterns were observed, as shown in the accompanying diagram.
Which one of the following conclusions is most appropriate based on the above observations?
A) There are three alleles of one locus and that the individuals with two bands are heterozygotes.
B) There are two alleles of one locus and that the individuals with two bands are heterozygotes
C) Population is present as hardy-Weinberg equilibrium
D) Population is not present as hardy-Weinberg equilibrium
