In humans, without considering the variation provided by crossing over, how much will two siblings from one set of parents vary
Mars2501 [29]

Answer:

Random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.

Explanation:

Sexual reproduction adds genetic variations in the progeny by crossing over, independent segregation of homologous chromosomes and random fusion of gametes. Without crossing over, independent segregation of homologous chromosomes towards opposite poles during anaphase I of meiosis may result in two siblings to vary from each other for 0-23 chromosomes.

There is an equal probability of each of the two siblings to get a chromosome from mother or father. Hence, irrespective of the variations provided by crossing over, random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.

Natalka [10]

Answer:

<em>The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances into the bloodstream.
