Question

(assertion):sexually producing individuals have two copies of genes for same trait (reason) : if the copies are not identical the trade that gets Express is called the dominant trait and the other is called the recessive trait​

Answer 1

Assertion is false, but reason is true.

Explanation:

• Sexually producing animals have two copies of genes for the same character ex: height. The two copies of the genes present could be AA( homozygous dominant ),Aa(heterozygous dominant ), aa (homozygous dominant ).

• Depending on the genetic recombination, that occurs during fertilisation, the paternal and maternal genes are combined and the combination they result in decides the character to be expressed.

• In copies that are non identical (heterozygous), the copy that expresses itself is called dominant trait and the other one which is not expressed is called recessive trait.

• The dominant trait gets expressed in both homozygous and heterozygous conditions, but the recessive trait gets expressed only in homozygous condition.

• Therfore, the assertion is false , reason is true.
