A genetic outcome of a genetic cross between the same parents is independent of previous outcomes.
<h3>What is genetic variation?</h3>
Genetic variation can be defined as the genetic poll of an organism, which is the raw material trough which evolution can occur by natural selection.
During sexual reproduction, the formation of gametes generates different genetic backgrounds which are independent of distinct gametes.
In conclusion, each genetic outcome of a genetic cross between the same parents is independent of all previous outcomes.

Answer:
D. Aa
Explanation:
Given:
Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa
Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa
Now if both cross and fertilization occurs, we have:
A a
a Aa aa
a Aa aa
The offsprings are (Aa, Aa, aa, aa)
Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.
Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).

Answer:
pangea
Explanation:
once all of the world was connected and we call that pangea then over time the continental plates moved making the earth formation we know now. the theory is that could the dinosaurs have moved while pangea was still a thing.
