What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
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).
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.
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 does rr mean eg fireblade rr?
what does r-r mean i mean rr
What has the author Christine Mary Coutts written?
Christine Mary Coutts has written: 'Period changes of RR Lyrae variables in the globular cluster M5' -- subject(s): Cepheids, Variable stars
Which variable stars have pulsation periods between 1.5 hours and 1.2 days?
RR Lyrae stars. (Sometimes these stars are classed as a type of "Cepheid variable", but they are usually considered as a separate star type.)
What type of star is lyra?
The star RR Lyrae is a special type of star, slightly smaller than the Sun, which pulsates in brightness. There are many stars of this type, and they are useful in astronomy because the period of variation depend on their mass and brightness, so they can be used as a standard candle. Asronomer look for RR Lyrae-type stars in globular clusters, and when they can find one it tells them the distance to that cluster, even if it's too far away to have its parallax measured.

What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
What is the difference between homozygous and herterozygous?
homozygous is where the 2 chromosomes are the same. ex- rr, RR heterozygous is where the 2 chromosomes are different. ex- Rr
