Evolutionary geneticists carefully genotype a population of saber-toothed tigers and find the following genotypes:

250 tigers are A1/A1, 500 tigers are A1 / A2, and 250 tigers are A2/A2.

Tragically, an asteroid lands in the middle of the population, killing 50% of each genotype.

A) What will the genotype frequencies be in the next generation?

Alden Oconnor · Answer 1

since 50% of each genotype was tragically destroyed, the new population will be as follows;

A1A1 = 125, A1A2 = 250, A2A2 = 125

The new genetic frequencies are as follows;

A1A1 = 125/500 = 0.25

A1A2 = 250/500 = 0.50

A2A2 = 125/500 = 0.25
