In order to obtain the. $F_1$ generation Mendel pollinated a pure-breeding tall plant with a pure breeding dwarf plant. But for getting the $F_2$ generation, he simply self pollinated the tall $F_1$ plants. Why ?
Mendel performed selfing among the $\mathrm{F}_{1}$ tall hybrids($Tt$)in order to segregate the two-traits.
Which of the following law was discovered first by Mendel?
Definitions / Explanation : Heterozygous
Assertion : Cross of $F_1$ individual with recessive homozygous parent is test cross.
Reason : No recessive individual are obtained in the monohybrid test cross.
If two opposite alleles come together, one finding morphological expression masking the other, the fact is described as law of
The alleles are
