What is dominant recessive?
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).
What is phenotype of 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.
How do you set this up Two heterodox red flowers (white flowers are recessive) are crossed.?
Rr X Rr = 1RR, 2 Rr, and 1rr
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
What is the phenotype of a purebred recessive?
A recessive trait is known as the characteristic that is the outward expression of the gene. Recessive traits can be masked by dominant traits but are still present if the gene is present in the organism.
What is the genotype Rr?
It is heterozygous. Heterozygous means that one allele is dominant and the other is recessive, Rr
How could a child be considered a hybrid?
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
What is dominant recessive?

Rr X Rr = 1RR, 2 Rr, and 1rr
What is the difference fom heterozygous and homozygous recessive?
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! :-)
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
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.
In genetics lowercase letters are usually used to indicate?
Lowercase letters in Genetics are usually used like Rr or rr, or RR. Lowercase letters usually represent a recessive trait.
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
Would Rr show a dominant or recessive phenotype?
dominant
Which alleles is the recessive alleles?
recessive alleles are the ones with small letters, for example in Rr, the recessive is the r.
