What is the phenotype of RR?
Besides, what is the genotype of RR?
A homozygous plant contains either of the following alleles for seed shape: (RR) or (rr). The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape.
Additionally, what is the phenotype of RR can roll tongue? A phenotype is a description of what an organism looks like based on its genotype. A person with the Rr genotype for tongue rolling would be able to roll his or her tongue, because he or she has the dominant allele that allows tongue rolling. So “tongue rolling” is his or her phenotype.
Beside this, what is the phenotype of a plant with genotype RR?
For this plant, the genotype for leaf color is RR , which is homozygous dominant, consisting of two dominant alleles. Since the only allele possible is dominant, the plant will express the dominant phenotype, which is red leaf color.
What is the genotype from the cross between RR and RR?
For example, a test cross between two organisms with same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr. And in this example, the predicted genotypic ratio is 1:2:1.
