प्रश्न
Is the presence of large number of chromosomes in an organism a hindrance to sexual reproduction? Justify your answer by giving suitable reasons.
उत्तर
The presence of large number of chromosomes in an organism is not a hindrance to sexual reproduction because number of chromosomes has no role in deciding a particular mode of reproduction. For example; there are 8 chromosomes in a somatic cell of a fruit fly, while there are 380 chromosomes in a somatic cell of a butterfly but both of them reproduce sexually.
