Identify the Mendel's Law that states that though the parents contain both the alleles, during gamete formation alleles will separate and each gamete will get only one allele.
Law of Dominance
Law of Independent assortment
Law of segregation
In Mendel's experiment, when tall pea plants were crossed with dwarf pea plants, F1 generation showed all tall plants (dominant trait). The recessive trait dwarfness did not get expressed because ________________
the allele responsible, produced normal enzyme for tallness.
the allele responsible, produced no enzyme for the expression of tallness.
