BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION
342045
The condition in which there are more than two set of chromosomes is called
1 Polytene
2 Aneuploidy
3 Monoploidy
4 Polyploidy
Explanation:
Polyploidy is a condition in which more than two sets of haploid chromosomes are present. This condition occurs due to abnormal cell division, either during mitosis or during metaphase -I in meiosis.

In man which of the following genotypes and phenotypes may be the correct result of aneuploidy in sex chromosomes
1 22 pairs + XXXY females
2 22 pairs + Y females
3 22 pairs + XX females
4 22 pairs + XXY males
Explanation:
Aneuploidy is the presence of an abnormal number of chromosomes in a cell. For example a human cell will have 45 or 47 chromosomes instead of the usual 46 in this condition. This chromosomal disorder involves the loss or gain of single chromosome. Klienefelter’s syndrome condition is presented by genotype 22 pairs + XXY males.

Number of autosomes present in skin cells of a human female is
1 22 autosomes
2 22 pairs
3 23 autosomes
4 23 pairs
Explanation:
The total number of chromosomes in a normal human cell is 46 (23 pairs). Out of these 22 pairs are autosomes and one pair of chromosomes are sex chromosome.
