Answer #1

Ans:- d) Al of these answers are correct

Allele frequencies in a population may change due to four fundamental forces of evolution:

Natural Selection,:- favourable traits are selected by nature and help there propagation and growth , in this way there allel frequency inceases

Genetic Drift:- Genetic drift, a change in the gene pool of a small population that takes place strictly by chance.

Mutation:- Mutation can change the allele frequency by favouring the survival of organism. Eg antibiotic resistance in bacteria

and Gene Flow.:- The movement and exchange of genes or alleles from one population of species to another.

In cats, curled ears result from an allele (Cu) that is dominant over an allele (cu) for normal ears. Black color results from an independently assorting gene (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. a. What is the phenotype and genotype of the F1 b. If an F1 mates with a stray cat that is homozygous for black and normal...

I am having a very hard time with allele frequencies unfortunately even though they seem to be relatively straightforward. this is the data set I am working with: #1: Adeyemo 2006. HbAA= 0.70, HbAS= 0.26, HbSS=0.04; population size = 5982 and I need to find the fitness of AA, fitness of Aa, and fitness of aa. AA is homozygous with wild type of allele for Sickle-cell anemia, Aa is heterozygous for the Sickle-Cell allele, and aa is homozygous for the...
