Hardy-Weinberg

Question 1

Explain the blending theory of inheritance

Answer 1

• offspring had characteristics intermediate between their parents
• hence variation would be diluted each generation

Question 2

Explain the Mendelian inheritance theory

Answer 2

• quantal
• hereditary units remain distinct during fertilisation

Question 3

What is the hardy Weinberg principle?

Answer 3

Allele and genotype frequencies remain constant over succeeding generations in randomly mating large populations unless perturbed by evolution

Question 4

Name the five assumptions of the hardy Weinberg principle

Answer 4

1. Reproduction is sexual and individuals mate at random
2. The population is very large (infinite)
3. Natural selection is not affecting the locus
4. Mutation is negligible
5. Migration does not occur

Question 5

P and Q are equal to?

Answer 5

P = proportion of the dominant allele
Q = proportion of the recessive allele
