Answer:
Frequency of heterozygous carriers of the allele in the entire herd is i.e
out of
Explanation:
It is given that a recessive allele pair produces a dwarf cow.
Let this recessive allele be represented by "t" and the dominant allele for tall height trait in cows be "T".
Given
Total population of randomly mating cows
Total number of dwarf calves in the population
Frequency of genotype "tt" producing dwarf calves is represented as in HW equilibrium equation.
Here
Frequency of recessive allele is equal to "q"
As per first equilibrium equation of HW,
Frequency of genotype "TT" producing dwarf calves is represented as in HW equilibrium equation.
As per HW's second equilibrium equation
Substituting the given values in above equation, we get -
Frequency of heterozygous carriers of the allele in the entire herd is i.e
out of
