The frequency of autosomal alleles K and k in a large population of snails is 0.6 and 0.4. What is the approximate genotypic fre
Flura [38]

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).

Proteins act as what in cells to control reactions
Damm [24]

The answer is; catalyst

These proteins are called enzymes. They work by lowering the activation energy of reactants and hence speed up the biochemical reaction. They are not affected in the process hence one enzyme molecule can catalyze many reactions. An example of such an enzyme is carbonic anhydrase that enables carbon dioxide to dissolve in blood plasma as carbonic acid.
