C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
E) If the assertion is false but reason is true
Correct Answer: A
Solution :
According to principle of segregation (first law of Mendelism), the two factors of a character which remain together in an individual do not get mixed up but keep their identity distinct, separate at the time of gametogenesis or sporogenesis, get randomly distributed to different offspring as per the principle of probability. Gametes carry a single factor or allele for a trait. The two Mendelian factors present in the \[{{F}_{1}}\]plants segregate during gamete formation. The principle of gametes because segregation of the two Mendelian factors of a trait results in gametes receiving only one factor out of a pair. As a result gametes are always pure for a character.
