Question

An offspring produced out of two parental stocks differing in two characters is called as___________

• A. Dimorphic
• B. Dihybrid
• C. Diploid
• D. Polyploidy

Answer 1

The correct option is B Dihybrid

• Dihybrid organism is heterozygous for two different genes i.e. it carries contrasting alleles of two different genes.
• For example, a tall plant with violet color flowers having genotype TtWw is a dihybrid as it carries both dominant and recessive alleles for two different traits (plant height and flower color).
• Any trait or character which exhibits two distinct forms is said to be dimorphic. For example, plant height exhibits tallness and dwarfism and thus is a dimorphic trait.
• A cell or organism carrying two complete sets of chromosomes is termed as diploid. For example, a human cell with two complete sets of 23 chromosomes i.e. 2n = 46 chromosomes is said to be diploid. The presence of more than two complete sets of chromosomes refers to as polyploidy.

Thus, the correct answer is option B.
