prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

Why are cells so small? In your answer, use the terms volume, distance, diffusion, surface area, plasma membrane.
Leno4ka [110]

Answer:

Cells are so little, so they can maximize their ratio of surface area to volume.

Explanation:

Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
