A. 0.3025 (AA), 0.495 (Aa), 0.2025 (aa)

B. 0.2500 (AA), 0.500 (Aa), 0.2500 (aa)

C. 0.5500 (A), 0.4500 (a)

D. 1.000 (AA), 0.000 (Aa), 0.000 (aa)

E. 0.333 (AA), 0.333 (Aa), 0.334 (aa)

Answer #1

Answer:Hardy Weinberg genotype fequency in a population is defined as the number of individuals of a given genotype divided by the total number of individuals in the population

Genotype counts of AA= 300

Genotype count of Aa = 500

Genotype count of aa = 200

Total count = 300 + 500 + 200 = 1000

Hardy weinberg genotype frequency of AA = 300/1000 = 0.3

Hardy weinberg genotype frequency of Aa = 500/1000 = 0.5

Hardy weinberg genotype frequency of aa = 200/1000 = 0.2

Since these values are closest to these values is in option A

The correct option is A. ( 0.3025 (AA), 0.495 (Aa), 0.2025 (aa) )

A hypothetical population ofcats has two alleles, TL and TS, for a gene that codes for tail length. The allele frequency of TL is 0.7 and the allele frequency of TS is 0.3. TLTL individuals have long tails. TLTS individuals have medium tails. TSTS individuals have short tails. The equation for Hardy-Weinberg equilibrium states that at a locus with two alleles, as in this cat population, the three genotypes will occur in specific proportions, described by the equation p2 +...

In 1783, a British sailing ship crashes on an island in the South Pacific. 100 individuals survive, only to discover that the island is already inhabited by a native population of 300. With no hope of returning home, they join the local population. A) In Great Britain, the allele frequency for blue eyes (b) is 0.8. If the native population is true-breeding for brown eyes (B, which has complete dominance over b), what is the new allele frequency for this...

You are studying two isolated populations of birds living on two different islands. In particular, you are interested in studying two different traits in these birds: beak size and feather color. Beak size is determined by a single gene exhibiting incomplete dominance. Birds with 2 copies of the A allele (genotype AA) have large beaks, birds with 1 copy of the A allele (genotype Aa) have medium beaks, and birds with no copies of the A allele (genotype aa) have...
