Question

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

Answer 1

Explanation:

(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)
