Answer:
D. Both Genetics and the Environment
Explanation:
Getting a pierced ear is both a genetic and environmental trait because, in males, it is not genetically transferred, rather it is a choice to manually pierce the ear maybe at birth, or much later in life. In females, however, pierced ears is a genetic trait because it is gotten naturally when they are born
These environmental factors include where a person stays, the kind of friends they keep, and people they try to imitate. Ear piercing is something that is done manually for males for various reasons.
Answer:
Option A
Explanation:
Given -
Man has X-linked recessive trait . Thus its genotype can be represented as
YX'
Woman has normal vision with homozygous genotype i.e "XX"
A cross is carried out between the above two parents thereby producing following offspring -
Y X’
X XY XX’
X XY XX’
Out of four offspring two are boy "XY" which do not have Red-Green Color blindness
While the two daughters "XX' " have Red-Green Color blindness
Thus, all the daughters produced have Red-Green Color blindness. Thus the chance of having a daughter with color blindness is 100 percent
