In humans, red blood cells have a number of proteins embedded in the cell membrane. One type of protein, the Rh factor, is contr

Reptile [31]

Answer:

The frequency of the Rh allele $= 0.90$

Explanation:

Given -

Rh is the dominant to Rh–

Therefore alleles for Rh will be represented by "p" and allele for Rh- will be represented by "q"

So , the frequency of the Rh– phenotype is 0.01.

Which means $q^{2} = 0.01$

Hence, frequency for allele of Rh–

$=\sqrt{q^2} \\= \sqrt{0.01} \\= 0.1$

As per Hardy Weinberg's first equation-

$p+q=1$

Substituting the value of "q" in above equation, we get -

$p+0.10=1\\p=1-0.1\\p=0.90$

So the frequency of the Rh allele $= 0.90$
