Question

Mendel found that the reciprocal crosses yielded identical results. From that he concluded that

• A. There is no dominance of any trait.
• B. Sex has no influence on the dominance of traits.
• C. There is independent assortment of traits.
• D. Sex plays a role in deciding the dominance of a trait.

Answer 1

Answer: (B)

Sex has no influence on the dominance of traits.

Reciprocal cross using male and female gametes for two different traits, alternating the source of gametes. Experimental dihybrid cross led to the law of independent assortment, which states that, the emergence of one trait will not affect the emergence of another. Or, the members of an allelic pair segregate independently of members of another allelic pair. All possible allelic combinations can occur in the reproductive cells. Mendel's law of independent assortment states that allele pairs separate independently during the formation of gametes. Therefore, traits are transmitted to offspring independently of one another.
