If an RR genotype is crossed with a Rr genotype, which color flowers would the offspring least likely have?
a.) red
b.)white
I think it would be white, but I'm not sure...
To determine the color of flowers that the offspring would least likely have when an RR genotype is crossed with an Rr genotype, we need to understand the basic principles of inheritance and the genetic makeup of the parent genotypes.
In this case, the RR genotype represents a homozygous dominant genotype, where both alleles are dominant and code for red flowers. On the other hand, the Rr genotype represents a heterozygous genotype, where one allele is dominant (R) and codes for red flowers, and the other allele is recessive (r) and codes for white flowers.
When these two genotypes are crossed, the possible genotypes of the offspring can be determined through a Punnett square.
R R
------------------
R | RR RR
r | Rr Rr
By examining the Punnett square, you can see that there are only two possible genotypes for the offspring: RR and Rr. Both genotypes have at least one dominant allele (R), which codes for red flowers.
Therefore, based on this genetic analysis, the offspring would be least likely to have white flowers (option b.) and more likely to have red flowers (option a.).
