A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge

Sophie [7]

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Explanation:

Given -

Purple flowers - 847

Pink flowers - 153

The frequency of recessive genotype i.e

$q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\$

Frequency of recessive allele i.e q is equal to

$q = \sqrt{0.153} \\q = 0.391$

As per hardy Weinberg's first equilibrium equation -

$p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609$

Frequency of purple homozygous species

$= p^2\\= 0.609^2\\= 0.371$

Number of purple homozygous species $= 0.371 * 1000= 371$

Number of pink homozygous species $= 0.153 * 1000= 153$

Heterozygous species is equal to

$(1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476$
