In a certain population of fruit flies, 640 out of 1000 have red eyes, while the remainder have sepia eyes. The sepia eye trait is recessive to red eyes. If the population is in H-W equilibrium, how many individuals would you expect to be homozygous for red eye color?

In a population of 1000 fruit flies, 360 have red eyes and the remainder have sepia eyes. The sepia eye trait is recessive to red eyes. How many individuals would you expect to be homozygous for red eye color if the population is in Hardy-Weinberg equilibrium?

00:01 Total number of fruit flies are given which is equal to thousand.
00:12 Out of them, red i flies are 640.
00:21 Then the remaining which ones are sepia, i flies, which is equal to thousand.
00:38 640 which is 360.
00:42 Now according to hardy winberg equation we know that p plus q is equals to 1.
00:58 So here p is the frequency of allele which is dominant allele and q is the frequency of frequency of recessive le...
