Question

HELP PLEASE!!

In rabbits, their ears can be either short or floppy, where short ears are dominant over
floppy ears. There are 653 individuals in a population. 104 rabbits have floppy ears and
549 have short ears. Find: the frequency of the dominant and recessive alleles and the
frequency of individuals with dominant, heterozygous, and recessive genotypes.

Answer 1

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

Given -
Short ears (S) is dominant over floppy ears.
Total population of rabbits
Population of rabbits with floppy ears
Population of rabbits with short ears
Frequency of rabbits with floppy ears is equal to

Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by
Thus,

Thus,

Frequency of rabbits with short ears only

Frequency of heterozygous rabbit (Ss)
