Question

Siblings are
A) sons and daughters of same parents
B) individuals formed through asexual means
C) individuals from an interspecific cross
D) mutants

Answer 1

Hint: We all know that when we talk about siblings we usually refer to human beings. The individuals are obtained as a result of reproduction. The siblings share a blood relationship.

Complete answer:
The word sibling was found in 1903 in an article in Biometrika in Germany. Siblings are those that share blood relationships. Studies suggest that identical twins appear to have more close relationships than fraternal twins. It is true about twins that they share a greater bond due to their upbringing together. So siblings are sons and daughters of the same parent.
- Interspecific cross: It involves the cross between two different species. It results in hybrids.
- Asexual reproduction does not involve the male and female gametes. It results in daughter cells.
- Mutants: They are the organisms obtained as a result of mutation.
- Therefore we can that sibling means sons and daughters of the same parents.

Additional Information:
i) HALF SIBLINGS- they are people who share one parent. They may have their mother or father in common.
ii) THREE-QUARTER SIBLINGS- They share one parent, while the unshared parents are first degree relatives to each other.Medically, a full sibling is termed as a first-degree relative and are 50% related and a half sibling is called a second degree relative and are 25% related.

Thus the correct answer is option ‘C’.

Note: Children or offspring raised together are termed as siblings . A male sibling is a brother and a female sibling is termed as a sister but if a relative has no siblings then it is termed as an only child. There are other terms relative to them like stepsiblings, adoptive siblings and siblings in law.
