What is the phenotype of a plant with genotype RR?

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 of 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. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.

What is the RR genotype ratio of the offspring?

It describes the number of times a genotype would appear in the offspring after a test cross. For example, a test cross between two organisms with the same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr. In this example, the predicted genotypic ratio is 1:2:1.

Is RR a genotype or phenotype?

The allele that produces red flower color (R) is not completely expressed over the allele that produces white flower color (r). The result in the heterozygous genotype (Rr) is a phenotype that is a mixture of red and white, or pink.

When a red RR flowered plant is crossed with white WW flowered plant all the off spring of generation are pink it indicates that R gene is?

The offsprings Rr are pink due to partial expression of both alleles, i.e. incomplete dominance.

What is RR Punnett Square?

RR or rr is a purebred trait. phenotype – Phenotype is the physical appearance of the organism. For example whether the organism is green, yellow, round, wrinkled, pink, blue etc. Here is the problem we are going to solve. In pea plants, round seeds are dominant over wrinkled seeds.

How do you cross RR and RR?

For a test cross between two organisms with the genotype Rr, there will be four possible results; RR, Rr, Rr, rr. This gives us a ratio of 1:2:1, which is the genotypic ratio for the cross between Rr and Rr.

How many squares are in a Punnett square for a two factor cross?

16 boxes
A two-trait Punnett Square has 16 boxes. The probability of a cross producing a genotype in any box is 1 in 16.

What will be the genotypic ratio of the cross RR and RR?

1 : 2 : 1
1 : 2 : 1.

What will be the genotypic ratio of the cross between RR and RR?
