In a large herd of 5468 sheep, 76 animals have yellow fat, compared with the rest of the members of the herd, which have white fat. yellow fat is inherited as a recessive trait. this herd is assumed to be in hardy-weinberg equilibrium. a. what are the frequencies of the white and yellow fat alleles in this population?

The Hardy-Weinberg equation is written as p²+q²+2pq = 1 and p + q =1

where,

p² is the frequency of homozygous dominant (BB)

q² is the frequency of homozygous recessive (bb)

2pq is the frequency of heterozygous (Bb)

p is the frequency of dominant allele (B)

q is the frequency of recessive allele (b)

As per given details, the number of homozygous recessive organisms in a population is 76.

Total population size is 5468

Thus, the frequency of homozygous recessive (q²) =

⇒ q² = 0.014

⇒q =

⇒q = 0.118

∴ p = 1 - 0.118

⇒p = 0.882

thus, the frequency of yellow fat allele is 0.118 and that of white fat allele is 0.882

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom

answer: the answer is b
