RR is red and WW is white. The offspring of a cross between an RR and a WW plant would be?
Make a punnet square.
W W
R WR WR
R WR WR
To determine the possible offspring of a cross between an RR and a WW plant, we need to understand the concept of dominant and recessive traits.
In this case, we know that RR represents a red trait, and WW represents a white trait. We can assume that the red trait is dominant (represented by R) and the white trait is recessive (represented by W).
When plants reproduce sexually, they inherit one allele (gene variant) from each parent. In this cross, since the RR is homozygous (having two identical alleles - R), and WW is also homozygous (having two identical alleles - W), the offspring will always inherit one R allele from the RR parent and one W allele from the WW parent.
Therefore, the offspring of an RR and WW cross would all have the genotype RW. However, since the red trait is dominant over the white trait, the phenotype (the physical appearance) of the offspring would be red, while carrying the white trait recessively.
In summary, the offspring would be red in color, but they would possess the genotype RW, indicating that they carry the white trait but do not express it phenotypically.
