If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
A human male can roll his tongue (genotype Rr) while his female partner cannot (genotype rr). What are the chances of any children they may have being able to roll their tongues?
The ability to roll one's tongue is a trait influenced by a dominant allele (R) and a recessive allele (r). The male with genotype Rr can pass on either the R or r allele, while the female with genotype rr can only pass on the r allele. Therefore, their children could inherit either Rr (able to roll their tongue) or rr (unable to roll their tongue), resulting in a 50% chance of having the ability to roll their tongues.
In a certain plant rough seeds R are dominant and smooth seeds r RECESSIVE two plants with genotype?

Use a punnet square to predict the results of a monohybrid cross starting with the phenotypic and genotypic r?
A punnet square is a 2x2 grid that is used to show the probability of an offspring showing a certain genotype and phenotype. The genotype is shown by using a letter for the trait. A capital letter is used to represent a dominant allele and a lowercase letter is a recessive. Ie: a heterozygous individual would be shown as having genotype Rr for a trait. If their genotype contains at least one dominant allele, then their phenotype is shown as the dominant trait. If the trait is eye color, R being dominant brown eyes, and r being recessive blue eyes, then the individual with either RR or Rr will have brown eyes. and if they have rr, then they have blue eyes. Now back to the punnet square, The top of the square will have the genotype of one parent, and the side will have another parent. If the father is RR, then each column will have a R over it. If they are Rr, then the first column will have an R and the second will have a r. Likewise, if they are recessive, then the top of the square will have rr. The same is shown on the rows on the side. The genotype goes down the two squares on the side. The genotype probability is found by crossing each allele in the boxes. If one box has R over it, and r to the right, then the box contains Rr. This is used to fill in all four boxes. In the end, If you have {RR, Rr, rr, rr} as your resulting genotypes, then there is a 50% chance that the offspring will have Dominant or recessive phenotype. The genotype ratio is then 1:2:1 and the phenotypic ratio is 2:2.
What is the genotype of a person that is homozygous non sicklier?
The genotype of a person who is homozygous non-sickler for sickle cell anemia would be HbAHbA, meaning they have two normal hemoglobin genes. This genotype does not carry the mutation that causes sickle cell anemia.
When crossing a Rr genotype with a rr genotype what will the ratio of RR to rr be in the resulting generation?
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.
Which one is recessive Rr or RR?
The recessive trait is represented by the genotype rr, where both alleles are lowercase. The genotype RR represents the dominant trait.
The phenotype of the rr genotype would be?
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.
What is the genotype of a carrier?
Rr heterozygous
Is Rr homozygous?
No, Rr represents heterozygous genotype as there are two different alleles (R and r) present. For a genotype to be homozygous, both alleles must be the same (RR or rr).
If R is dominant to r the offspring of the cross of RR with rr will be homozygous?
R R r Rr Rr r Rr Rr That is the Punnet Square. The genotype will be 100% Rr in the cross. The phenotype will be whatever phenotype is constituted by your dominant allele.
What is the genotype of a red flower crossed with a blue flower?
The genotype would depend on the genetic makeup of the red and blue flowers. If red is represented by 'RR' and blue is represented by 'bb', the offspring would all be Rr (heterozygous) for the flower color gene.
A pea plant with round seeds has the genotype Rr you cross this plant with a wrinkled seed plant genotype rr what is the probability that the offspring will have wrinkled seeds?
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
A human male can roll his tongue (genotype Rr) while his female partner cannot (genotype rr). What are the chances of any children they may have being able to roll their tongues?
The ability to roll one's tongue is a trait influenced by a dominant allele (R) and a recessive allele (r). The male with genotype Rr can pass on either the R or r allele, while the female with genotype rr can only pass on the r allele. Therefore, their children could inherit either Rr (able to roll their tongue) or rr (unable to roll their tongue), resulting in a 50% chance of having the ability to roll their tongues.
What is the genotype for sickle cell anemia?
