Answer:
Crossing over and random alignment are the events of meiosis-I that add new gene combinations to the gametes. Random fusion of male and female gametes is called random fertilization.
Explanation:
During the pachytene stage of meiosis-I, part of the chromatids of each of the homologous chromosomes of a bivalent is broken apart and exchanged. This exchange of the genetic material between the members of a bivalent is called crossing over. The recombinant chromatids formed by crossing over have new allele combinations that were otherwise not present in the parental chromatids.
During metaphase I, the homologous pairs are aligned at the cell's equator in a random manner. This means that either the paternal or maternal chromosome of a pair may face one or the other pole of the cell. The arrangement of chromosomes during metaphase-I determines whether the paternal or maternal chromosome of each pair would be distributed to one or the other pole of the cell. This random segregation creates new gene combinations in gametes.
All the gametes have equal chances of getting fused with a gamete from the opposite gender. This is called random fertilization and further adds variations.
Answer:
The correct answer is option-C
Explanation:
Anastosomes is a connection between the two interconnected tubular structures like in the loops of intestine or the blood vessels.
The anastomy between the blood vessels is known as the circulatory anastomosis. The connection is formed between the arteries and arteries or between veins and veins or between arteirs and veins.
The anastosome connections forms the bypass route for the flow of blood if one pathway of blood id blocked.
Thus, option-C is the correct answer.
