Question

Select the wrongly matched pair.

• A. Hybrid - Pure breeding progeny.
• B. Incomplete dominance - An exception to Mendelism
• C. Heredity - Transmission of characters from one generation to the next
• D. Allele - Alternate representation of a gene

Answer 1

The correct option is A Hybrid - Pure breeding progeny.

Pure breeding varieties are the one that carries same allele for a particular character and pass the trait without change from one generation to next upon selfing (for example, pure breeding tall (TT) plant carries two copies of “T” allele). Hybrids are the one which carries contrasting allele of a particular gene e.g., hybrid tall plant’s genotype is “Tt”. Incomplete dominance refers to the conditions where none of factors of a gene is dominant; the phenotype of heterozygous dominant individual is blend of dominant and recessive traits. Thus, it is an exception to Mendel’s principle of dominance. Heredity is genetic transmission of characters from parent generation to progeny. Alternative forms of a gene are called alleles e.g., alleles for gene for plant height are “T” and “t”. Thus, the correct answer is option A.
