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.

<span>the most likely diagnosis for the fetus regarding the condition is Heterozygous carrier.It means having two unique alleles at relating loci on homologous chromosomes. A person who is heterozygous for a characteristic has acquired an allele for that quality from one parent and an elective allele from the other parent.Inheritance of the maternal mutant haplotype predicts that the fetus is a carrier</span>
Option A
A locus is the singular form of Loci and its depicts the location of a gene on the chromosome.
