A recessive allele causes phenylketonuria (PKU) when homozygote. If the frequency of the recessive allele is 0.05 in the populat
Radda [10]

Answer:

0.095

Explanation:

Phenylkentonuria is a disease caused by a recessive allele.

The frequency of the recessive allele + the frequency of the dominant allele equals 1.

The frequency of the recessive allele is q = 0.05

The frequency of the dominant allele then is p = 1  - q = 0.95

If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .

2pq=2× 0.05 × 0.95

2pq=0.095

The heterozygote frequency in the population is 0.095

Revise this sentence by replacing all gerunds with infinitives.
vekshin1

Answer:

Please see below

Explanation:

I always tell people that I love to dance, to write and to paint.

The verb keep cannot take an infinitive afterwards so it is better to replace that expression  altogether with another one that means the same thing, but that can use an infinitive. The verb love can take either gerunds or infinitives afterwards with only a subtle variation in the meaning.
