Question

What happens to the character do not expres itself phenotypically in F1 generation, in a monohybrid cross.​

Answer 1

Answer:

According to the law of dominance, a heterozygous individual carries two contrasting alleles/ factors of a gene. Here only one allele can express itself in the individual. It is called as dominant allele. The allele which does not show itself in a heterozygous individual is known as recessive allele. Each character in an organism is controlled by a gene which has two alleles. Hence this law suggest that each character of an organism is represented by atleast two factors and that one allele (dominant allele) shows its effect in both homozygous and heterozygous condition while the other one (recessive) shows itself in homozygous condition only. Options B, C and D can be explained by this law. The law of segregation states that two alleles for one gene do not blend with each other.

So, the correct answer is 'Alleles do not show any blending and both the characters recover as such in F2 generation'.
