The law of segregation of characters postulated by Mendel can be related to
1 A gamete receiving only one of the two homologous chromosomes during meiosis
2 The presence of two genes for each character in a somatic cell
3 Presence of both genes on the same chromosome.
4 None of the above
Explanation:
It is also known as law of purity of gametes

Diploid cells have
1 Two chromosomes
2 Two sets of chromosomes
3 One set of chromosomes
4 Two pairs of homologous chromosomes
Explanation:
Diploid cells are the cells which have two complete sets (2n) of chromosomes. In diploid organisms, one set of chromosomes is donated by each parent that makes up the two sets in the offspring.

Which statement is true for Law of Segregation
1 Characters are controlled by discrete units called factors
2 Factors or alleles of a pair segregate from each other such that a gamete receives only one of the two factors
3 Mendel crossed the tall plant from \({F_2}\) with a dwarf plant. This he called a test cross.
4 Hybrids contain alleles with contrasting traits, they are called homozygous.
Explanation:
only option 2 is related to law of segregation.

The allele which does not express in the \(F_{1}\) generation in presence of another allele is
1 dominant
2 co-dominant
3 incompletely dominant
4 recessive
Explanation:
Only dominant characters are expressed by dominant genes, in F1 generation, while recessive genes and their expressions are suppressed.
