In a certain variety of onions, pungent smell (P) is completelydominant to subtle smell (p), yellow (A) is completely dominant towhite (a), and large bulb (B) is completely dominant to small bulb(b). For the following crosses and results, what are the genotypesof the parents?
- pungent, large x subtle, large. 3â„4 pungent, large; 1â„4pungent, small
- subtle, white x subtle, yellow 1â„2 subtle, white; 1â„2 subtle,yellow
- yellow, large x white, small 1â„4 yellow, large; 1â„4 white,small; 1â„4 yellow, small; 1â„4 white, large
- subtle, white, large x pungent, white, large. 1â„2 pungent,white, large; 1â„2 subtle, white, large
- subtle, yellow, large x subtle, yellow, small. all subtle,yellow, large
What phenotypic ratio is expected from a crossing an onion ofgenotype Pp Aa bb with an onion of genotype PP aa Bb?
