Question: In a population of beetles, the frequency of the dominant allele A at a locus is 0.8. If the population has 400 individuals, what is the expected number of A alleles in the gene pool?
Can some please explain to me in detail how deal with the 400 individuals, I always get confused when a the number of individuals is given in population. Please help me.
Homework Answers
Please look in the image for solution:
now there is also an
alternative for such questions:
You calaculate A frequency first. As given in image it is 0.8
Now multiply this allelic frequency with ( 2× number of total individuals)
= 0.8 × ( 2 × 400)
= 0.8 × 800
= 640 alleles of A in population out of total 800 alleles
( We multiply with 2 multiply by total number of individual for calculating number of alleles.)

An Amazon rainforest population of leaf beetles has 100,000 individuals.
An Amazon rainforest population of leaf beetles has 100,000 individuals. The beetles exist in two color morphs, purple and green. Purple beetles live on epiphytic orchid blooms whereas the green beetles inhabit the leaves of the orchid plants. The color is controlled by two alleles at a single gene locus. The purple allele (P) is dominant to the green allele (p) 36% of the beetle population is green and the other 64% of the population is purple. Assuming the population...

that:

A population of flour beetles has 1000 individuals. Normally the beetles are red in color; however, this population has a utation in the gene for body color that results in black beetles that are designated by the rr genotype. Red body color is dominant to black so the genotypes RR and Rr result in red beetles. Assume the population is in Hardy-Weinberg equilibrium, with a 50% frequency of each allele for body color. A) --- what is the frequency of...

-Does the frequency of an allele in a population have anything to do with whether or not an allele is dominant or recessive? Why? -What process does play a role in determining the frequency of a given allele in a population? -Choose either the earlobe shape gene or the widow's peak gene. Assuming that natural selection is the primary force contributing to the frequency of the two alleles of that gene, provide a hypothesis as to why the particular allele...
