Choose the correct answer:
1. In Mendel's experiments with garden pea, round seed shape (RR) was dominant over wrinkled seeds (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy). What are the expected phenotypes in the F2 generation of the cross RRYY x rryy? (NEET - 2006)
2. The production of gametes by the parents the formation of zygotes, the F1 and F2 plants can be understood using (NEET - 2019)
3. Two genes R and Y are located very close on the chromosomal linkage map of maize plant. When RRYY and rryy genotypes are hybridised, then F2 segregation will show: (NEET - 2007)
