The correct option is B Reproduce sexually
Mendel's law of genetics is applicable only in plants which reproduce sexually. In Mendelian genetics he explains about the independent assortment which results in the formation of gametes which has the contrasting characters from both male and female parents. It will be expressed according to its zygosity and dominant traits. if the recessive trait is present in its homozygous form, the character will be expressed. At the same time, dominant character will be expressed in both homozygous and heterozgous forms. Pisum sativum which Mendel chose was a sexually reproducing plant.
