The recessive genes located on X-chromosomes in humans are always-
1 Sub-lethal
2 Expressed in males
3 Expressed in females
4 Lethal
Explanation:
Recessive genes located on X-chromosomes in humans are always expressed in males because males have only one X-chromosome, and there is no corresponding second -chromosome to mask the expression of the recessive gene, as is the case in females who have two X-chromosomes.

Which of the following is suitable for experiment on linkage?
1 aaBB aaBB
2 AABB aabb

Explanation:
Exp. B Linkage can be shown by a cross between homozygous dominant AABB and homozygous recessive aabb (AABB aabb).

Crossing over is the exchange of genetic material between
1 Non-sister chromatids of the homologous chromosomes
2 Sister chromatids of the homologous chromosome
3 Chromatids of non-homologous chromosome
4 The genes those are completely linked
Explanation:
Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis. This genetic recombination results in offspring with unique combinations of traits.

When two genetic loci produce identical phenotypes in cis and trans position they are considered to be :
1 pseudoalleles
2 multiple alleles
3 the part of same gene
4 different genes
Explanation:
When two genetic loci produce identical phenotypes in both cis and trans positions, they are considered pseudoalleles. This means that even though they are separate genetic loci, they function as if they were alleles of the same gene because they produce the same observable traits.

Which one of the following information is essential to determine the genetic map distance between two genes located on the same chromosome?
1 Length of the particular chromosome
2 Number of genes present in the particular chromosome
3 Number of nucleotides in the particular chromosome
4 Percentage of crossing over or recombinant frequency between the two genes
Explanation:
Percentage of crossing over or recombinant frequency between the two genes is essential to determine the genetic map distance between two genes located on the same chromosome. This information helps estimate the relative distance between the genes based on the frequency of genetic recombination events during meiosis.
