Question

state and explain the law of dominance with suitable example​

Answer 1

Answer:

Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.

Explanation:

Mendel thought, maybe one gene suppressed the other or prevented the other gene from expressing it. And thus he devised the law of dominance which states that:

“In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.”

So, if there exists two contrasting traits, one of the traits will always suppress the other, thereby expressing itself. T suppresses t, thus making the offspring plant tall.

Such a trait is known as a Dominating trait. The suppressed trait is known as Recessive trait. Also, the recessive trait freely expresses itself in the absence of the dominant state. And this is what Mendel’s Law of Dominance is all about.

So in the pea plant, the seed color yellow always dominates seed color green. seed shape round always dominates seed shape wrinkled. So here, round (RR) and Green (GG) are the dominant traits whereas wrinkled (rr) and yellow (gg) are recessive trait.

Thanks for the question.

Hope it helps you.

Answer 2

Answer:

Law of dominance:-

▶️a cross between a pure breathing red flowering pea plant and pure breeding white flower pea plant produce red flower plant in F1 generation red flower colour is dominant over the white colour.

▶️this last states that out of two factor representing difference rate of tractor only one extracts itself please factor or allele which is able to expression which is able to express itself in the generation is called dominant allele

refers to the attachment ☺️
