Rr x Rr is an example of what type of cross?
Dihybrid cross
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.
What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
O neg and O pos parents what happens to children?
The genotype for Rh positive blood is either RR or Rr and the genotype for Rh negative blood is rr. Since the child gets one gene from each parent, they have the possibility of being either.
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).
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
Which one is recessive Rr or RR?
Rr
When crossing a Rr genotype with a rr genotype what will the ratio of RR to rr be in the resulting generation?
50%Rr to 50%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
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.
Is handedness passed through genetics?
simple Mendelian genetics...right-handed is the dominant allele (R), left-handed is recessive (r). you can figure it out using a Punnett square. RR, Rr = RH kid rr = LH kid RR + RR = 100% RR -> all RH kids RR + Rr = 50% RR, 50% Rr -> all RH kids Rr + Rr = 25% RR, 50% Rr, 25% rr -> 75% RH kids, 25% LH kids rr + rr = 100% rr -> all LH kids to be LH, you have to have left-handedness somwhere in the family. however, you can be LH and neither your parents or grandparents would have to be.
