25%,1:3 This is due to the heterozygous condition to produce on homozygous long and one homozygous short then two heterozygous short.ie 1:2:1,but short is dominant and heterozygous short ate taken to be short ,thus modifying the ratio to 1:3,1:3 is 25%:75%.therefore homozygous long is 25%.
It is necessary to increase oxygen delivery in order to maintain sustained ATP production.
Answer:
<em>A mutation in his offspring</em>
Explanation:
A mutation can be described as any change which occurs in the DNA of an organism. Mutations can be either heritable or non-heritable
If a mutation occurs in the gamete cells of a male, the mutation will be heritable and will occur in his offsprings.
Other options, like option D, is not correct because a mutation in the gamete cells will not cause a mutation in the somatic cells. Gamete cells are the sex cells and hence mutation will arise in the sex cells.
