Question 1

Evolution by natural selection Assumptions of the model?

Answer 1

• Non-overlapping generations
• Pre-adult survival affected by a gene with two alleles (A, a)
• Individuals are haploid (they carry A or a)
• Asexual reproduction

Question 2

Evolution by natural selection Variables?

Answer 2

• N: population size at birth

* p: frequency of A allele at birth (a allele at frequency = 1 – p)

Question 3

Evolution by natural selection Parameters:?

Answer 3

• wA: survival probability of offspring with A allele
• wa: survival probability of offspring with a allele
• R: number of offspring produced by surviving adults
