Chromosomal mechanism of sex determination in human beings is called
1 heterogamesis
2 haemopoiesis
3 transgenesis
4 parthenogenesis
Explanation:
Chromosomal mechanism of sex determination in human being is called heterogamesis. It is XY system, the females are homogametic with a pair of \(\mathrm{X}\) chromosome (XX) and males are heterogametic with one \(\mathrm{X}\) and \(\mathrm{Y}\)-chromosomes (XY).

Diploid cells have
1 two chromosomes
2 one set of chromosomes
3 two pairs of homologous chromosomes
4 two sets of chromosomes
Explanation:
Diploid cells have two sets of chromosomes, with one set inherited from each parent. This is in contrast to haploid cells, which have only one set of chromosomes.

In human sex determination the key factor is
1 X - chromosome
2 autosome
3 sex chromosome
4 Y-chromosome
Explanation:
In human sex determination, the key factor is \(\mathrm{Y}\)-chromosome. The presence or absence of the Ychromosome determines whether an individual develops as male (Y-chromosome present) or female (Ychromosome absent).

An example for sex influenced inheritance:
1 Haemophilia
2 Colourblindness
3 Baldness
4 Down's syndrome
Explanation:
A example of sex influenced inheritance is baldness. Sex influenced traits are controlled by genes present on autosomes. It has different intensity of expression in two sexes.
