Answer:

Option (b).

Explanation:

The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.

The heterozygote frequency can be calculated by the formula:

F = \frac{2Kk-H}{2Kk}

Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.

Put the values in the above formula

0.3 = \frac{2\times2\times0.6\times0.4-H}{2\times0.6\times0.4}

H = 0.36 ≈ 0.34.

Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.

Hence, the correct answer is option (b).

brilliants [131]

Answer:

The correct answer is - option C.

Explanation:

The case in this the biological exterminators asks to use the biological concept which includes spraying the solution of the juvenile hormone to get rid of nymphs of specific insect and according to the assumption, this solution causes some alteration on the ability to reproduce of such nymphs and leads to only nonreproductive ones.

On the given condition the increasing of nymphs, the number of adult nymphs or decreasing of nymphs can not be condition and as the reproductive ability is affected the number of nymphs would be the same.

Thus, the correct answer would be - option C.

If you want to selectively label RNA being synthesized by cells(and not DNA) what radioactive compound would you add to the medi
romanna [79]

The right answer is E.

Uracil is a nitrogenous base (pyrimidine) specific for RNA. The nucleoide of uracil is called uridine and nucleotide is called uridine monophosphate or uridylate. In the DNA, there is thymine instead of uracil.

So if we mark the uracils, only the RNA will be marked. The DNA will not be given that there is no uracil in it.
