Rufina [12.5K]

N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on

a. inheritance of natural variations

b. inheritance of acquired characteristics

c. natural selection

d. survival of the fittest

Inheritance of acquired characteristics. Thus, option "B" is correct.

<h3 /><h3>What is inheritance of acquired characteristics?</h3>

For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.

Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution

What is the difference between genotype and phenotype
dlinn [17]

Answer:

  • person’s <u>genotype</u> is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. <u>Phenotype</u> is the detectable expression of this genotype – a patient’s clinical presentation.

Explanation:

person’s phenotype results from the interaction between their genotype and their environment.

The connection between genotype and phenotype is not always clear-cut. This means that you may encounter disparities between your patient’s genomic test result and their clinical presentation. Similarly, the phenotype of patients with a given genetic condition may vary greatly even within families.
