a large population of land turtles on an isolated island has two alleles for a gene that determines shell thickness go forth in their shells is dominant over the allele for sickle shares the thinner shell Elia appears at a frequency of 20% assuming there is no net advantage to fix a thin shell what should the frequency of homozygous sticker shelled turtles be in the population

Step 1
The frequency of the t allele is given as 20%, or 0.2. Since there are only two alleles for this gene, the frequency of the T allele must be 80%, or 0.8 (because the total frequency of all alleles for a gene in a population is always 1). The frequency of Show more…

A large population of land turtles on an isolated island has two alleles that determine shell thickness: The allele for thinner shells is dominant. The allele for thicker shells occurs at a frequency of 20%. Assuming the population is in Hardy-Weinberg equilibrium, what should be the frequency of homozygous individuals with thicker shells? (Hint: Use a Punnett square to calculate the answer: 16%, 50%, or 64%)

A population of turtles in Hardy-Weinberg equilibrium, two alleles control what colour of shells is produced. F is dominant, producing brown shells, and f is recessive giving yellow shells. When the population was observed 64% of individuals have brown shells. Using 44109 as the population size, 1. Calculate the number of homozygous dominant turtles in the population. 2. Calculate the number of heterozygous turtles in the population.

A population of turtles is found where dark shells are completely recessive to light shells (denoted by the alleles a and A). In your survey you captured both dark shelled turtles (452) and light shelled turtles (478). 1. 0.717 2. 0.283 3. 0.303 4. 0.486 5. 0.514 6. 0.697 What is the genotypic frequency of light shelled individuals in the population? What is the frequency of the a allele?
