Answer:

The frequency of the number of individuals with the dominant phenotype is 0.84

Explanation:

in Hardy-Weinberg equilibrium equation, <em>p</em> & <em>q</em> are used to represent the frequency of alleles in a population.

Frequency = Total No of 1 allele / total alleles

if frequency of <em>p</em> allele = 0.6

therefore <em>p</em> + <em>q</em> = 1        ==> <em>q</em> = 0.4

To get these frequencies, square (p + q)

<em>p</em>² + 2<em>pq</em> + <em>q</em>² = 1

The proportion of individuals that are homozygous dominant for B allele is p²

<em>P</em>² = 0.6 x 0.6 = 0.36

The proportion of individuals that are heterozygous for B and b alleles is 2<em>pq</em>

2<em>pq</em> = 2 x 0.6 x 0.4 = 0.48

The frequency of number of individuals with dominant female type

= 0.36 + 0.48 = 0.84

Answer:

The frequency of the dominant (normal) allele in the population (p) is simply 1 - 0.02 = 0.98 (or 98%). The percentage of heterozygous individuals (carriers) in the population.

What would happen if (G) guanine lined up with (T) thymine during meiosis. Please help me with this.
ivann1987 [24]

Answer:they won't for a pair

Explanation:Basically it all depends on process called complementary base pairing, the structure of thymine and adenine is such that it forms two hydrogen bonds and therefore pair up

2.guanine and cytosine have such structure that they form three hydrogen bonds and pair up

So Adenine complements only thymine and guanine complements cytosine and there aren't any chances of guanine pairing up with thymine.
