In the field of botany, the radicle refers to the initial component of a seedling, (a developing plant embryo) to originate from the seed at the time of the germination process. The radicle is the embryonic root of the plant and develops downward in the soil.

It is the initial thing to arise from a seed and down into the ground to permit the seed to take up water and conduct it to its leaves so that the process of photosynthesis can start. The radicle originates from a seed via the micropyle.

How can two parents who show the dominant trait have offspring who shows the recessive trait? Give an example to support your an
natta225 [31]

Answer:

One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin. Let (S) represent the dominant allele, and (s) represent the recessive allele. Only (ss) individuals will express a smooth chin. To determine the probability of inheritance of a smooth chin (or any other recessive trait), the genotypes of the parents must be considered. If one parent is heterozygous (Ss) and the other is homozygous recessive (ss), then half of their offspring will have a smooth chin.
