In an island lizard population with 1000 individuals, throat color is determined

Question

In an island lizard population with 1000 individuals, throat color is determined by a single gene locus with two alleles producing two different colors: green and blue, with green being dominant; 91% of the lizards have green throats.

8. Assuming Hardy-Weinberg equilibrium, what should be the frequency of the blue allele in this population?
a. 0.09 b. 0.3 c. 0.6 d. 0.10

9. How many heterozygous individuals should you see in this lizard population?
a. 90 of the 1000 should be heterozygous (0.09%)
b. 420 of the 1000 should be heterozygous (42%)
c. 490 of the 1000 should be heterozygous (49%)
d. 810 of the 1000 should be heterozygous (81%)

Explanation / Answer

c. 490 of the 1000 should be heterozygous (49%)
