Chromosome abnormalities usually happen as a result of an error in cell division. Mention any two effects of such abnormalities in real life.
Dear Student,
Chromosomal abnormality occurs during cell division which leads to unequal distribution of chromosomes in two daughter cells. chromosomal abnormality can occur both during Mitosis (Equational cell division) and Meiosis (Reductional cell division).
Chromosomal abnormality during Mitosis occurs in autosomes while in case of Meiosis it occurs in sex chromosomes.
Various diseases have been reported in Humans related to chromosomal abnormality:
1. Down Syndrome (47 chromosomes): Here 21st chromosome is present as an extra copy.
2. Turner Syndrome (45 chromosomes): Here only a single sex chromosome is present i.e. only one X chromosome.
Regards
