Answer: Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Explanation:
The average height of the oceans surface between high and low tides is called the sea level. It is important to know this measurement because with this it is possible that we can calculate the height of anything on the land. Also, we can <span> calculate the height of anything on the land. Also, we can be able to determine whether the oceans are falling or rising through time.
So the answer is </span><span>Sea level </span>

Answer:
50% or 1/2. The result remains unchanged if the husband were to have G6PD.
Explanation:
For X-linked recessive inheritance, a female (XX) needs two recessive alleles to be affected while a male needs only one (XY). It is hypothetically assumed that the Y chromosome does not carry any trait.
Assuming the allele for the disease is represented by g, a woman whose father suffered from G6PD is a carrier for the disease with genotype
. A normal man will have the genotype
. When the 2 marries:
x
=
It thus means that 50% or 1/2 of their sons will be expected to have G6PD.
Now, assuming the husband has G6PD, the mating becomes:
x
=
50% or 1/2 of their sons is still expected to have G6PD. The ratio remains unchanged.
