Question

Mendel showed that unit factors, now called alleles, exhibit a dominant/recessive relationship. In a monohybrid cross, the .......... trait disappears in the first filial generation. (a) dominant (b) codominant (c) recessive (d) semi-dominant Select the correct answer from above options

Answer 1

Answer is : (c) recessive Gregor Mendel studied inheritance of traits in pea plants. In a monohybrid cross, the recessive trait disappears in the first filial generation. The traits that were visible in the F1-generation are referred to as dominant traits. This happens because recessive allele does not express itself in the presence of dominant allele.
