Name the pair of genes responsible for a particular characteristic in an individual.

The number of chromosomes in parents and offsprings of a particular species remains constant. due to

When the maternal and paternal chromosomes carry different alleles at the same locus, the genotype is called

Pairing of homologous chromosomes is called :-

Assertion : Pairing and separation of pair of chromosomes would lead to segregation of a pair of factors they carried Reason : Two alleles of a gene pair are located on similar sites on non-homologous chromosomes

Assertion :- Mendel proposed that in a true breeding, tall or dwarf pea variety the allelic pair of genes for height are identical i.e. TT and tt respectively. Reason :- Alleles can be similar as in the case of homozygotes or can be dissimilar as in the case of heterozygotes.

A cross involving two pairs of alleles is

Identify the correct statement : (a) Female of many birds has a pair of dissimilar ZW chromosomes, while the males posses a pair of similar ZZ chromosomes.

Even if a character shows multiple allelism, an individual will only have two alleles for that character. Why?
