Explanation:
Answer:
15.21 %
Explanation:
If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:
p + q = 1
p² + 2pq + q² = 1
where;
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
Given that p= 0.68 and q = 0.39
the percentage of the homozygous recessive genotype (q² ) will be
(0.39)² = 0.1521
= 0.1521 × 100
= 15.21 %
∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %
The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.
<h3>What is the Hardy Weinberg principle?</h3>
The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.
The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).
This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and q^2 the recessive homo-zygous frequency.
In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

Answer:
We keep animals to provide us with:
1. wool and hair for clothing, ropes and tents
2. hides and skin for leather.
3. meat, milk, eggs
4. bones, hooves and horn for a variety of uses.
5. Some animals are used for transport, ploughing and work.
6. We always benefit from the animals we keep.
These are the "Uses of some animals".

The answer is ‘arteries are less flexible’. This is why the older you get the more predisposed you
are to cardiovascular diseases such as high blood
pressure. However, regular
exercise may delay this development. The barometers in the blood vessels also
become less sensitive hence these vessels become less responsive to blood
pressure changes.
