Answer:
The Apocine glands.
Explanation:
These glands secrete sex pheromones This is the chemical substances which exhibits subtle effects on the sexual behavior and physiology of other people.
They are located at the axilla,anogenital region, at the areola and the nipple etc,The breast is a modified apocrine gland.It contains the mammary gland which secrets the best milk.Thus it is an example of apocrine gland.Basically,pheromones are has a significant reproductive effect on the opposite organism concerned.It aids mating,
Their hormonal secretions is released through the plasma membrane by budding off from the extracellular membrane,
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.
