How would you write the correct scientific name for humans
guapka [62]

The Latin names for individual species are written using a system termed "binomial nomenclature" that was developed originally by Linnaeus. Quite literally, each species is identified by a combination of "two names": its genus name and its specific epithet. A familiar example is that of human beings, Homo sapiens.

"If the frequency of an allele in a population is 0.999, what is the expected frequency of homozygotes for this allele in a popu
IgorC [24]

Answer:

The answer to the question is

The expected frequency of homozygotes for the allele in a population at Hardy-Weinberg Equilibrium is 0.998

Explanation:

From the question, we have the frequency of an allele  =  0.999

By Hardy-Weinberg Equilibrium

p² + 2pq + q² = 1 and p + q = 1

p = dominant allele frequency  in the population

q = recessive allele frequency  in the population

p² = homozygous dominant individuals  percentage

q² = homozygous recessive individuals  percentage

2pq = heterozygous individuals percentage

Therefore the frequency of the homozygotes for the allele = 0.999² =  0.998001 ≅ 0.998 to three decimal places

The Hardy-Weinberg equilibrium states that the genetic disparity in a population will remain unchanged from generation to generation in the absence of evolutionary disturbing influences
