Mendel’s Law of independent assortment holds good for genes situated on the:

Occasionally, a single gene may express more than one effect. The phenomenon is called:

In a certain taxon of insects some have 17 chromosomes and the others have 18 chromosomes. The 17 and 18 chromosome-bearing organisms are:

The inheritance pattern of a gene over generations among humans is studied by the pedigree analysis. Character studied in the pedigree analysis is equivalent to:

It is said that Mendel proposed that the factor controlling any character is discrete and independent. His proposition was based on the

Two genes ‘A’ and ‘B’ are linked. In a dihybrid cross involving these two genes, the F1 heterozygote is crossed with homozygous recessive parental type (aa bb). What would be the ratio of offspring in the next generation?

In the F2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are:

Mother and father of a person with ‘O’ blood group have ‘A’ and ‘B’ blood group, respectively. What would be the genotype of both mother and father?

One of the genes present exclusively on the X-chromosome in humans is concerned with
