Question

HELP ME ASAP PLEASE ANSWER

Four o’clock flowers can be red (RR), white (rr), or pink (Rr). If a pink flower and red flower are crossed, what will be the phenotypic ratio?
100% pink
50% red, 50% pink
100% Rr
50% RR, 50% Rr

Answer 1

Rewrite what's noted

• Red(RR)
• white(rr)
• Pink(Rr)

As pink and red are crossed white is out of business.

So

Share will be halved

• 50% pink :50% red
• 50% Rr:50% RR
