Solved in 2 steps
- Does inbreeding affect allele frequencies? Why or why not? How does it affect genotype frequencies? With regard to rare recessive diseases, what are the consequences of inbreeding in human populations?You find a population of 200 mice in which 32 of them display the recessive fur color. What is the genetic structure (the allelic and genotypic frequencies) in that population, with respect to fur color?Suppose in a certain population there are 100 individuals homozygous for the A1 allele, 400 individuals homozygous for the A2 allele, and 500 heterozygous individuals. What are the genotype frequencies? What are the allele frequencies?
- What impact do cases a multiple alleles have on the number of kinds of phenotypes displayed in the population?Evolution is a change in the allele frequencies that occur in an individual over time. True or false?Calculate allele frequencies in a population of 200 dominant homozygotes (TT), 50 heterozygous (Tt) and 100 recessive homozygous (tt). (see image for table)
