Question

Discuss a dihybrid cross involving RRTT (red tall) and rrtt(white dwarf).

Answer 1

gametes	RT	Rt	rT	rt
RT	RRTT-Red and Tall	RRTt-Red and tall	RrTT-Red and tall	RrTt-Red and tall
Rt	RRTt-Red and tall	RRtt-Red and short	RrTt-Red and tall	Rrtt- Red and short
rT	RrTT-Red and tall	RrTt-Red and tall	rrTT-White and tall	rrTt-White and tall
rt	RrTt-Red and tall	Rrtt-Red and short	rrTt-white and tall	rrtt-white and short

Gametes formed by the parents :

Parent 1(RRTT) = RT

Parent 2(rrtt) = rt

Progeny of F11 generation will be-

9:3:3:1:: Red and tall: Red and short: White and tall: white and short.
