Can a woman with type a Rh negative blood have a healthy baby with type b Rh positive blood?
A baby is a person. Soooooo they have attitudes that vary each day. So some days the baby could be "negative" or "mad", but they could also be very happy. Rh positive is dominate (R gene), Rh negative is recessive (r gene). I mom is Rr and dad is either Rr or rr, then baby could be rr giving Rh negative blood type.
Rr x Rr is an example of what type of cross?
Rr x Rr is an example of a monohybrid cross, specifically a cross between two heterozygous individuals for a single trait. This type of cross helps determine the possible genotypic and phenotypic outcomes for the offspring.
What does RR mean in blood type?
Without any other numbers or letters added yet to indicate the rest of the Rh phenotype, two upper case R's indicate that the person has a double dose (or homozygous) D antigen. The person is Rh positive with the genotype being DD rather than heterozygous Dd.
What are the phenotypes and genotypes of the offspring from the mating of a red carnation and a pink carnation for incomplete dominance?
The red color is RR and pink is Rr. RR is red, rr is white and Rr is pink. Cross the two: RR (red) and Rr (pink). You will get RR and Rr in a 1:1 ratio. You will not get any rr (white).The red color is RR and pink is Rr. RR is red, rr is white and Rr is pink. Cross the two: RR (red) and Rr (pink). You will get RR and Rr in a 1:1 ratio. You will not get any rr (white).
Are RR Lyrae stars and RR Lyrae variables different?
RR Lyrae variables are variable stars often used as standard candles. RR Lyrae are pulsating horizontal branch stars.
O neg and O pos parents what happens to children?
If both parents are O negative and O positive, their children may inherit various blood types depending on their parents' genotype. However, all children will carry at least one O antigen in their blood type. The parents could have children with blood types O negative, O positive, A negative, A positive, B negative, B positive, AB negative, or AB positive.
How do you identify the genotyped of the parents when the Offspring has Rr Rr rr rr?
using a punnett square the parents would have to be Rr and rr
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
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.
If both parents are 0 positive and child is A negative?
This is grounds for divorce, I'm here to tell you. I can understand the Rh factor. Call the gene R. If the parents were both Rr, there's a 25 percent chance the kid could be rr and therefore negative. The blood type itself is the problem. O is recessive--you've got to have both blood type genes set to O to be O. If both parents are O there's not an A gene in the whole family, hence no way to produce an A baby.
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.
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.
