उत्तर
Male and female gametes are produced through meiosis and have the same number of chromosomes. So, the number of chromosomes in the female gamete of a tobacco plant will be 24.
Since a zygote is formed by the fusion of male and female gametes, it would contain double the number of chromosomes than male or female gametes. So, the number of chromosomes in the zygote of a tobacco plant will be 48.
