Question

Why do brothers and sisters (who are not identical twins) from the same parents usually have different combinations of traits?

विकल्प

• Because one parent's genes are always stronger.

• Because 50% of genes they inherited from each parent randomly.

• Because their traits change as they grow older.

• Because they live in different environments.

Answer 1

Because 50% of genes they inherited from each parent randomly.

Explanation:

While a child gets half the genes from each parent, the random selection of which genes are passed on creates a unique mix for every sibling.
