Rr
It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. Is dominant. dominant can be RR or Rr. but when its recessive its rr.
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.
The resulting generation will have a 1:1 ratio of RR to rr genotypes when crossing an Rr genotype with a rr genotype, as each parent will contribute one allele to the offspring.
When crossing two heterozygous red flowers (Rr), you would use a Punnett square to determine the possible genotypes and phenotypes of the offspring. In this case, the genotypes of the parents are Rr x Rr. The possible offspring genotypes would be RR, Rr, and rr, with a phenotypic ratio of 1 red : 2 pink : 1 white flower.
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
a hybrid in animals is when a dominant gene in one parent (pure bred RR) and recessive gene in another parent (pure bred rr) combine.Rrin the punnett square:R Rr Rr Rrr Rr Rr
It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. Is dominant. dominant can be RR or Rr. but when its recessive its rr.
The genotype Rr represents an individual that carries one dominant allele (R) and one recessive allele (r) for a specific trait. This individual is called heterozygous for that trait.
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.
In genetics, you can either have a dominant allele (A) or a recessive allele (a). Being homozygous means that you have both of either a dominant or a recessive allele (ie you are either AA or aa). If the trait is a recessive trait, then you need to have it be homozygous recessive in order to express that trait. Hope this was helpful! :-)
To figure this out, use a Punnet Square.First, set up a test cross, like this:Rr x rrThis shows what you are crossing. Now you can make a Punnet Square.R rr Rr rr There is a 50/50 chance that the corn plant will have thegenotype rr.r Rr rr
The resulting generation will have a 1:1 ratio of RR to rr genotypes when crossing an Rr genotype with a rr genotype, as each parent will contribute one allele to the offspring.
Lowercase letters in Genetics are usually used like Rr or rr, or RR. Lowercase letters usually represent a recessive trait.
In this scenario, the red flower (R) is dominant, while the white flower (r) is recessive. The pink flower (Rr) is a result of incomplete dominance. When crossing a pink flower (Rr) with a white flower (rr), the possible offspring genotypes are Rr (pink) and rr (white). The Punnett square for this cross would look like this: R | r ---------------- r | Rr | rr ---------------- r | Rr | rr The phenotypic ratio would be 50% pink and 50% white flowers.

When crossing two heterozygous red flowers (Rr), you would use a Punnett square to determine the possible genotypes and phenotypes of the offspring. In this case, the genotypes of the parents are Rr x Rr. The possible offspring genotypes would be RR, Rr, and rr, with a phenotypic ratio of 1 red : 2 pink : 1 white flower.
In a cross between two heterozygous pea plants (Rr x Rr), where "R" represents the dominant allele for smooth seeds and "r" represents the recessive allele for wrinkled seeds, the probability of producing wrinkled seeds (rr) can be determined using a Punnett square. The genotype ratio from this cross is 1 RR : 2 Rr : 1 rr. Therefore, the probability of producing wrinkled seeds (rr) is 1 out of 4, or 25%.
