Title: What are the possible phenotypes of four offspring of plants?
Post by: riverviewguit on Feb 26, 2013
If a homozygous, recessive, white flowered plant is bred with a heterozygous (white, recessive and red, dominant) plant, what is the possible phenotype of four offspring?

The possible phenotypes are white (homozygous) white (homozygous) red (heterozygous) and red (heterozygous)

Two of the four offspring would be heterozygous (red dominant, white recessive), ant two would be homozygous (white recessive).
If the recessive trait is a, and the dominant trait is A, then it would look like aa x Aa, which means that there can be Aa, aa, Aa, aa.

Depends on the alleals of each plant if it's Hh and Hh 75%H 25%h HH and hh 100% H Hh and hh 50%H 50%h so it depends which set it is to what the offspring will be

F1 : Rr-red (hetrozygous)
F2 : 1 RR: 2Rr: 1rr - 3 red and 1 white
