Biology: Water is an example. of a pure substance a) true b) false

itorres40 · Accepted Answer

frequency of dominant and recessive alleles - 0.6, 0.4

frequency of individuals with dominant, heterozygous and recessive genotypes - 0.36, 0.48, 0.16

Explanation:

Given -

Short ears (S) is dominant over floppy ears.

Total population of rabbits = 653

Population of rabbits with floppy ears = 104

Population of rabbits with short ears = 549

Frequency of rabbits with floppy ears is equal to

$\frac{104}{653} \\= 0.159$

Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by $q^2\\$

Thus,

$q^2 = 0.159 =0.16\\q = \sqrt{0.16} \\q = 0.4$

Thus,

$p = 1-q\\p = 1-0.4\\p= 0.6$

Frequency of rabbits with short ears only

$= p^ 2 \\= 0.6^2\\= 0.36\\$

Frequency of heterozygous rabbit (Ss)

$p^2 + q^2 + 2pq = 1\\0.16 + 0.36 + 2pq = 1\\2pq = 1 - 0.36-0.16\\2pq = 0.48$
