Question

In sexual reproduction, an offspring is produced with genes from both parents. When the offspring has a new genetic variation that it got from neither of its parents, it is called
A.
a phenotype.
B.
a mutation.
C.
an autosome.
D.
a recessive gene.

Answer 1

Answer: Mutation


Explanation: mutation is a change in the sequence of DNA.

Answer 2

Sexual reproduction is a type of reproduction in which an organism is produced as a fusion between the gametes of a male and female.

This type of reproduction causes hereditary variability in the progenies because of the recombination of genes.

The correct answer is:

Option B. Mutation.

This can be explained as:

• Phenotype is a noticeable quality an individual obtains from the parent. So, it is not the correct answer.

• Any chromosome different from the sex chromosome is called an autosome. So, this option is also incorrect.

• A recessive gene is present in the DNA that gets concealed in the presence of the dominant gene. Hence this is also incorrect.

• The mutation is the modification or alteration in the nitrogen base of genetic material that can cause disease.

Therefore, a mutation occurred in the offspring.
