There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dom
viva [34]

Answer:

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

p = 0.7

Thus,

q = 1-p\\q = 1 - 0.7 \\q = 0.3\\

As per Hardy Weinberg's second equation of equilibrium -

p^2 + q^ 2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.7^ 2+ 0.3^2 + 2pq = 1\\2pq = 1- 0.49-0.09\\2pq = 0.42

So the total number of heterozygous individual is equal to

0.42 * 500\\= 210

11Alexandr11 [23.1K]

Answer:

Mist is made of water vapor.

Explanation:

The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.
