Question

Which one of the following can be explained on the basis of Mendel’s Law of Dominance?

1. Out of one pair of factors one is dominant and the other is recessive.
2. Alleles do not show any expression and both the characters appear as such in F₂ generation.
3. Factors occur in pairs in normal diploid plants.
4. The discrete unit controlling a particular character is called factor.
5. The expression of only one of the parental characters is found in a monohybrid cross.

Choose the correct answer from the options given below:

पर्याय

• B, C and D only

• A, B, C, D and E

• A, B and C only

• A, C, D and E only

Answer 1

A, C, D and E only

Explanation:

One allele is expressed above the other in a heterozygote, according to Mendel’s Law of Dominance, which is shown in the monohybrid cross when only one paternal trait is displayed. Mendel also highlighted the paired nature of these factors in diploid organisms and developed the idea of separate hereditary units known as factors (now known as genes), all of which are essential to understand inheritance patterns.
