<u><em>Chromosomes</em></u> asserts that our genes set the boundaries within which we can operate
Organisms that use oxygen need it for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility and reproduction.
The other 10% of the energy disappears like magic
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell.
Answer:
A) incomplete dominance.
Explanation:
It is a clear case of incomplete dominance. This kind of inheritance shows deviation from Mendel's popular law of genetics which is known as "Law of Dominance". This law states that when two pure breeding parents i.e. homozygous dominant and homozygous recessive are mated then all their off-springs are genotypically heterozygous but phenotypically they all show dominant trait. But in incomplete dominance, <u>the dominant allele is unable to mask the expression of recessive allele completely</u> which leads to a phenotype which is a blend of both the traits.
In the example, orange beak is unable to mask the expression of ivory beak completely as a result of which all the off-springs have an intermediate trait which is pale, ivory-orange beak.
