What do you predict will be the generations it will take for the C locus heterozygosity to get to the 1/2 of the recent or in other words current value?

I want the results to be described in words.

Among a large population of 2 million gray mosquitoes, one mosquito is heterozygous for a body color gene; this mosquito has one gray allele and one blue allele. There is no selective advantage or disadvantage between gray and blue body color. All of the other mosquitoes carry two copies of the gray allele. A. What is the probability of fixation of the blue allele? B. If fixation happens to occur, how many generations is it likely to take? C. Qualitatively, how would the answers to parts A and B be affected if the blue allele conferred a slight survival advantage?

in a randomly mating laboratory population of Drosophila, 4% of the flies have black bodies, and 96% have brown bodies. Flies with brown bodies always have at least one parent with a brown body. What is the frequency of heterozygotes in this population?     0.04     0.16     0.08     0.32   The period gene of Drosophila melanogaster encodes for a stretch of Thr-Gly repeated in tandem. In natural populations, the three most common alleles encode for 17, 20 and 23 Thr-Gly repeats.  The amplification by PCR of the allele encoding for 20 Thr-Gly repeats produces a fragment of 320 bp. Using the same set of primers, what is the size expected when amplifying the 17 Thr-Gly allele?     317     303     314     302       in a certain species of plant loci A, B and C have an additive effect on the colour of the flower. Alleles A, B, and C are dominant and alleles a, b and c are recessive.  Knowing that a plant with genotype AAbbCc has a…

1. The following table gives data for the frequency of genotypes in a population of sunflower plants from a coastal sage scrub community over the course of 50 generations. Gene products of the A allele produce stems without hairs, while gene products of the a allele produce stems with short hairs but flowers with many infertile stamens, and the a' allele produces stems with dense hairs and flowers with all fertile stamens. Note that it may cost the plants greatly in extra carbon to produce these hairs. At the onset of this survey, an invasive insect species that feeds upon the buds of sunflowers had been accidentally introduced into the habitat of this plant population. This insect makes its living by ascending the stems of herbaceous plants rather than landing upon the flower stalks or stems. Thus, dense hairs would impede the ability of this insect to reach the buds. Interpret the results of the data and explain how natural selection might be driving the genotype frequencies in this…

How do I identify the two types of SCO in my data set and determine the distance between them then draw a linkage map
