Question

A population of wild flowers contains plants with red, pink or white flowers. Flower color is known to be determined by two alleles segregating at a single gene locus. Given the following information, answer parts a, b and c. Estimate the proportion of the alleles for flower color in the parent flowers. Be sure to say which color goes with which allele. P(red) = P(white) = What percentage of the three flower colors would you expect if the color genotypes were in Hardly - Weinberg equilibrium? Red Pink White Using number of seeds per flowers as a measure of fitness, estimate the relative fitness of the three flower types. Red Pink White

Explanation / Answer

White -------W allele,red-------w
White genotype -------WW allele,
red-------ww,
pink-Ww
according to hardy weinberg law
p2 + 2pq + q2 = 1
Red: 2/100 = 0.02
Pink: 56/100 = 0.56
White: 42/100 = 0.42




By using gene count method
Allele frequency = p + q = 1
frequency of White -------W allele= WW+2Ww= p2 + 2pq/2=
= 0.02 + (0.5)(0.56)
= 0.3
======================
frequency of red -------w allele= ww+2Ww= p2 + 2pq/2=

= (0.42)+ (0.5)( (0.56) = 0.7
p + q = 1= 0.3+0.7

b) p2 + 2pq + q2 = 1
p =0.3, q=0.7
Red= ww= p2 = 0.09
Pink =Ww= 2pq = 0.42
White= WW= q2 = 0.49

c) Red: 10/16 = 0.625
Pink: 15/16 = 0.934
White: 20/16 = 1.25
white having more relative fitness value
