MCQ
When a cross is made between two parents with respect to a single character, it is called as:
- ADihybrid
- BMonohybrid
- CTrihybrid
- DNone of these
✓
Answer
- Monohybrid
Explanation:
A monohybrid cross is a type of cross between two individuals with different alleles at one genetic locus of interest.
The character(s) being studied in a monohybrid cross are governed by two or multiple alleles for a single locus.
A dihybrid cross is a cross between two pure lines (varieties, strains) that differ in two observed traits. In Mendelian sense, between the alleles of both these loci, there is a relationship of complete dominance - recessive.
Trihybrid cross is the mating of two individuals, organisms, or strains that have different gene pairs that determine three specific traits or in which three particular characteristics or gene loci are being followed.
