Question

1.Consider a population of 100 birds: 79 birds have red wings, and 21 have yellow wings (rr). Using the Hardy-Weinberg equation, determine the phenotype, allele, and genotype frequencies. Be sure to show your work!

2 .According to the Hardy-Weinberg principle, allelic frequencies will remain constant over time if certain assumptions are met. List those assumptions here:

3.Consider a population of 100 birds: 79 birds have red wings, and 21 have yellow wings (rr). Using the Hardy-Weinberg equation, determine the phenotype, allele, and genotype frequencies. Be sure to show your work!

4. In order for natural selection to occur certain conditions must be met. List those conditions:

Explanation / Answer

1. 'Hardy-Weinberg equation

p2+ q2 =1

p2+ (0.21)2=1

0.0041-1= 0.95

p2=0.95 q2=0.21

These are allelic frquencies

p2+2pq+q2=1

0.95+2pq+ 0.21= 1

2pq=0.16

pq=0.8

2. Hardy- Weinberg theory states that the genotype frequency and the allelic frequency remains same throughout the generations. For this to happen there there are five assumptions.

a. mutations sholud not occur

b.No selection of the partner. there should only be random mating for the maintenence,

c. No migration or transfer of gametes

d. population should be large

e. No natural selection between the population.

4. Natural selection is a process in which the strongest one will survive in the environmmet defeting the week species. This is also called survival of the fittest.

Conditions fro natural selection.

a. Reproduction

b. Heredity

c. variation if fittness

d. Variation in characters
