Answer:
Correct answer is (a). Local extinction
Explanation:
Local extinction is a type of relationship which result to competition between organism. A condition that makes organisms to battles for survival which may results to termination of kind of organism or group of kind of organism.
In an ecological niche, some organisms takes advantage of others, they tend to thrive and exploit others to survive while the one that can not compete go into extinction when the environment is no longer conducive due climatical change or pressure from the other organisms.

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.
