Answer:
The answer is mother in meiosis II
Explanation:
nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.
According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.
Answer:
<em>Evidence from the geological record is consistent with the physics that shows that adding large amounts of carbon dioxide to the atmosphere warms the world and may lead to: higher sea levels and flooding of low-lying coasts; greatly changed patterns of rainfall2; increased acidity of the oceans 3,4,5,6; and decreased.</em>
