Question

Suppose a starting population contained six individuals. Each pair of individuals had a different genetic makeup (genotype) from the others (genotypes: G-1, G-2, and G-3). The genotypes vary with respect to reproductive rate and offspring survival. Suppose G-1 has 8 offspring that survive to reproduce, G-2 produces only 4 surviving offspring over its lifespan, and G-3 leaves 12 surviving offspring.

a) If the average individual produces 8 offspring by the end of its lifespan, will the reproductive differences among genotypes alter the population growth rate?

b) How would the reproductive difference among genotypes alter the genetic composition of the population by T9?

c) Suppose that offspring descended from G-3 survive better and reproduce more successfully than all other genotypes in every generation. What might happen to the relative frequency of this genotype by T500?

Explanation / Answer

Comment successfully posted: a) It shouldnt change cuz your average is already 8 anyway in the first generation b) you would have more G3 cuz they make more babies c) all the other genotypes suck compared to g3 so they will become rare or even extinct by T500 cuz the awesome g3 will dominate!
