In a population of mice, there are two alleles of the A locus (A1 and A2). Tests showed that in this population there are 300 mice of genotype A1A1, 200 of A1A2 and 250 of A2A2. What is the frequency of the A2 allele in the population? (enter as decimal- with zero & rounded to nearest hundredth)

    Question 2: In an outbreeding diploid population, an autosomal locus has two alleles, A1 and A2. You observe the allele frequencies of A1 and A2 are both equal to 0.5, and the relative fitnesses of the three genotypes (A1A1, A1A2, and A2A2) are equal to 2, 1.5, and 1, respectively. A) Which allele will become fixed in this population? (1 point) **The recessive beneficial allele A2A2 will eventually become fixed in the population (A2A2=1) B) What is the allele frequency...

    In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...
