Red-green colour blindness in human is caused by an X-linked recessive allele if the trait occur in 4 of the males in a population at Hardy-Weinberg equilibriumthen the frequency of this allele is?

If 4% of males in a population have red-green color blindness, then the allelic frequency is 4% in males and in females. If mating is random, then in females, 92.16% do not carry the allele on either X chromosome, 7.68% carry the allele on one X chromosome, and 0.16% carry the allele on both X chromosomes. We have the dominant allele with frequency p and the recessive allele with frequency q, so 0.9216 + 0.0768 + 0.0016 = p^2 + 2pq + q^2 = (p + q)^2 = (0.96 + 0.04)^2

In a survey 16 women out of 20 000 were found to be colour blind What is the expected frequency of colour blind males in this population?
Not all forms of color blindness are hereditary. There are three distinct types of hereditary color blindness, each with different frequencies in the human population, and with distinct genetic causes. Red-green color blindness is more common among males than females, but blue-yellow color blindness is not. Talking about color blindness in general, there is no reliable ratio of male-to-female prevalence.
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.
What effect does natural selection have on the allele frequency of a population?
In the next generation that trait increases in frequency above the frequency in the current generation.
On what does the allelic frequency in a population depend?

What happens when a population is in weinberg equilibrium?
Allele frequency is stable
What is the frequency of color blindness in the general population?
Color blindness is not blindness; it is the inabilty to tell certain hues from certain other hues. It can be mild to severe. Red/Green color blindness is the most common. Probabaly about 5% of the general population in some degree. Data has been produced about specific populations and samples; however, there are no definitive global statistics. .

What effect does a bottleneck have on the allele frequency of a population?
It greatly reduces the total population, which increases the effects of genetic drift on allele frequency.
What causes a frequency in a population to change after each generation?
Gene mutation causes the phenotype frequency in a population to change after each generation.
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.
How will the allele change in the rat population?
Evolution is the change in allele frequency over time in a population of organisms. Rats too!
What effect does natural selection have on the allele frequency of a population?
In the next generation that trait increases in frequency above the frequency in the current generation.
