Answer:
genetic drift
Explanation:
Genetic drift is an evolutionary force that requires the presence of a small population. It is a random process that fixes one or other alleles randomly in the gene pool of a population. Genetic drift does not take account of survival fitness imparted by alleles to the individuals. Since random and chance events such as the death of all the individuals having a certain allele in a population affect the small population more intensely, genetic drift works on small populations only.
Consider this:
Each parent has two sex chromosomes.
The mother, as a female, has chromosomes XX.
The father, a male, has XY.
The mother will pass on one sex chromosome to the baby, as will the father.
The mother can only pass on an X.
The father, however, has a 50/50 chance of passing on an X or Y.
XX would make a female and XY would make a male.
Simply put, the sex chromosome from your mother is fixed, it's going to be an X no matter what. It's which sex chromosome your father passes on that determines your sex.
Answer:
1
Explanation:
why ?
size - very large compared to other planets
Its relative closeness (compared to other stars)
High reflective albedo of the light colored clouds
The fact that it is never inside Earth's orbit means that it is always mostly illuminated from our point of view regardless of relative positioning.
