Answer:
Meiosis I, a reductional division of two haploid cells produces offspring cells that are not genetically identical with the event of recombination. Haploid girl cells have half the original/parent cell chromosomes.
Explanation:
meiosis II, an equational or mitotic division, divides the haploid cells created in meiosis I to produce four identical daughter cells that ultimately form the male/female gametes (egg/sperm).
Here chromatids split in contrast to meiosis I when homologous chromosomes apart.
Answer:
Option (4).
Explanation:
Chromosome may be defined as highly compact DNA structure. The eukaryotic chromosome of different parts like centromere, short arm, long arm of chromosome and telomeres.
The telomeres are the DNA sequences present at the end of chromosome. These telomeres do not code for the proteins and get shorten after each round of replication. Telomeres are responsible for ageing in the living organisms.
Thus, the correct answer is option (4).
There are 46 chromosomes in every cell, except the cells in your genitals, such as in the ovaries and the sperms where there are 23
The answer would be a. Thyroid hormones control metabolism.
