Vedclass · Answer

(A) Hybrid plants are typically $F_1$ hybrids produced by crossing two genetically distinct parent lines. According to Mendel's Law of Segregation,the alleles for traits segregate during gamete formation. When $F_1$ hybrid plants are self-pollinated or cross-pollinated,the offspring ($F_2$ generation) show a segregation of traits,leading to a loss of the uniform hybrid vigor and specific phenotypic characteristics observed in the $F_1$ generation. Therefore,farmers must purchase new hybrid seeds every year to ensure the desired traits are maintained. Thus,both the Assertion and the Reason are correct,and the Reason correctly explains why hybrid characters are not maintained.

$A$ : Hybrid seeds have to be produced every year because seeds collected from hybrid plants,if sown subsequently,do not maintain hybrid characters.
$R$ : Hybrid seeds show segregation of traits.
