Dominant and recessive genes effect on phenotype

1 answer:

4 0

Dominant is the first gene variant in a phenotype from the two alleles of a gene and recessive has effect on the third allele of a phenotype.

Explanation:

The genetic phenomenon of masking of chromosome with one variant of allele or predominating the impact of one gene on its chromosomal copy is Dominance. In this phenomenon the first variant of gene is known as ‘dominant’ and the second one is ‘recessive’.

This phenomenon is not inherited by phenotype, it has a relative effect on two alleles of a gene where one is dominant on other and the recessive is on third allele. Dominant allele has functional protein but recessive does not have it.

In the normal course of evolution and adaptation, what is the most likely way for wings to develop in a tetrapod (four-limbed or

serious [3.7K]

The correct option is this: The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.

Adaptation refers to the physical or behavioral traits that an organism develop in order to enhance its suitability to its environment. Evolution on the other hand is always brought about by natural selection; organisms that are well adapted to their environments are naturally selected to survive, reproduce and pass their beneficial traits to their offspring. This is a gradual process that occurs over a long period of time.

For wings to develop in a four limbed organism, the organism has to start using the hind or the fore limbs for flight (New adaptive behavior). The genes that support this new behavior will be passed to its offspring and subsequent generations over a long period of time, until the wings are perfectly suited for flight.
