When a genetic population follows Hardy-Weinberg Equilibrium (HW), it states that certain biological tenets or requirements must be met. Given so, then HW states that the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimal. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = frequency of homozygous dominant individuals, 2pq = frequency of heterozygous individuals, and q^2 = frequency of homozygous recessive individuals.
So the problem states that homozygous dominant individuals (p^2) account for 60%, or 0.60. Thus the square root (sr) of p^2 = p or the dominant allele frequency in the population. So sr(p^2) = sr(0.60) -->
p = 0.775 or 77.5%
Homozygous recessive individuals (q^2) account for 20%, or 0.20. Thus sr(q^2) = q or the recessive allele frequency in the population. So sr(q^2) = sr(0.20) --> q = 0.447 or 44.7%
But since 44.7% + 77.5% = 122.2%, which is not equal to 1, we have a situation in which the allele frequencies do not match up, therefore this population cannot be determined using the Hardy-Weinberg Equation.

T-G-A-G-G-T-C-T-C-C-T-C T-G-A-G-G-T-C-A-C-C-T-C What type of mutation is depicted in this sequence?
kap26 [50]

Answer: The mutation is substitution.

Explanation:

There are three main types of mutation:

Substitution, deletion, and insertion.

We would be able to tell right away if the second sequence had an insertion or deletion, because it would have a different number of letters than first sequence. However, it does not. Both sequences have 12 letters.

But, the 8th letter in the first sequence (T) is different from the 8th letter in the second sequence (A).

This is substitution.

Which organism in the chart below is most distantly related to the other organisms?
Mamont248 [21]
In the chart provided below, you can see that the first species belongs to the plant kingdom, and the other three belong to the animal kingdom. The kingdom is a very high level of classification, right below the level of domains. Therefore, organisms that belong to different kingdoms are very distantly related.
