Pure-bred round-yellow pea seeds have genotype RRYY and the pure-bred wrinkled-green pea seeds have genotype rryy. Keeping this in mind, write the phenotypes of the following genotypes of hybrid pea seeds:

(a) Rryy


(b) rrYy


(c) rrYY


(d) RrYy


(e) RRyy

(a) Round-green (RR-round; dominant, yy-green; recessive)

(b) Wrinkled-yellow (rr-wrinkled; recessive, Yy- since one dominant gene Y Is present- yellow)


(c) Wrinkled-yellow (rr-wrinkled; recessive, YY-yellow, dominant)


(d) Round-yellow (Rr-one gene dominant R is present-round; Yy- since one dominant gene Y is present- yellow)


(e) Round-green(RR-round; dominant, yy-green; recessive)
