Principles of I...

Mendel’s “factors” that remain stable over generation to generation is now called as

Genes which code for a pair of contrasting traits are known as

Chromosomes are structure in nucleus that appeared to double and divide

Two alleles of a gene pair are located on homologous site on

Map distance of genes on chromosome is calculated by

Blender experiment to prove DNA as genetic material was performed by

Traits controlled by genes present on X-chromosome are called

When two genes present on different loci produce the same effect when present alone but interact to form a new trait when present together are called

Assertion: Duplicate genes are two or more genes found on different chromosomes which produce the same or nearly same phenotypic effect in the dominant state.
Reason: Duplicate genes produces same intensity of effect even when present together.

Statement I: Physical association between two genes located on same chromosome is called linkage.
Statement II: The generation of non-parental gene combination is called recombination.
Statement III: Recombination is essential for generation of new traits in a species.
