The chromosomal mutation in the zygote can be traced back to which of the following? (4.3, 4.4)Immersive Reader

lawyer [7]

The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".

<u>Option: B</u>

<u>Explanation:</u>

In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.

Chromosomal mutations are often caused by chemical agents or by mutagens. The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.
