These sorts of studies can help researchers determine the relative importance of nurture and nature in determining a trait. Nature here would refer to genetics passed down to an individual from its parents, whereas nurture refers to the environment the individual is exposed to.
The answer is: from mother
In a human diploid somatic cell (2n), there are<span> in total 46 chromosomes</span> - 22 autosomal chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes. In males, there is one X and one Y chromosome (XY) while in females, there are two XX chromosomes (XY).
During the formation of gametes, a female could give only X chromosomes, so gametes from the mother contain one X chromosome. But, a male could give X or Y chromosome, so gametes from the father contain either X or Y chromosome.
Female gamete and male gamete fuse to form a zygote. Male zygote must contain both X and Y chromosome. It inherits Y chromosome only from the father, so X chromosome must be inherited from the mother.
A. green ; black
The sensory cells present on our retina that are responsible for our vision are known as rod cells and cone cells. Rod cells do not allow us to see in color, only black and white, and are better in low-light conditions. Cone cells are responsible for our ability to see colors but are bad in low-light conditions. Cone cells are able to sense red, green and blue colors. When one type of the cells will be stimulated, the remaining will show an "afterimage" due to the overstimulation of the complementary cells.
