What is the probability that two heterozygous parents would have an offspring that produced round seeds?
The probability is 3/4 or 75%. If both parents are heterozygous for the seed shape trait (e.g., Rr), there is a 50% chance that each parent will pass on the dominant allele (R) for round seeds to the offspring. The probability of inheriting the dominant allele from both parents and producing round seeds is therefore (1/2) x (1/2) = 1/4 or 25%. Since there are two possible ways to inherit the dominant allele (from either parent), the total probability is 2 x (1/4) = 1/2 or 50%.
What is the principle of dominance?
The Principle of Dominance states that some alleles are dominant and some alleles are recessive. The dominant trait dominates or presents the expression of the recessive trait. Thus, for round seed: (capital) R - round (small) r - wrinkled RR - pure round Rr - hybrid round rr - pure wrinkled
What is rr cubed simplify?
rr cubed is r6rr cubed is r6rr cubed is r6rr cubed is r6
How do you calculate the minute ventilation?
vt x rr
How do you calculate QTcB?
QTcB = QT / (RR)1/2
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
What gametes will be produced by each parent RR x rr?
The genotype is always the "gene formula", in this case Rr.The phenotype is the expression of the genes (how the animal or plant looks, functions, or behaves). In this case, it's a bit hard to say what the phenotype would be without knowing what R is!If the question is about garden peas, and if R is the dominant allele responsible for round seeds, and r the recessive allele producing wrinkled seeds, then the genotype Rr will produce the phenotype of the dominant allele, i.e. round seeds.
Why do you need to look at genetics at both organismal and molecular level?
If you look at how Mendel studied his pea plant seeds, he saw that RR and Rr genotypes of seeds produced round seeds and rr produced wrinkled. This is from a phenotypical (or you can say organismal) level. However, when scientists cracked open these seeds, it was found that the Rr genotypes had only 50% of a protein, but it still looked round. RR had 100% of the protein, and rr had 0% of the protein. This is a case of Incomplete Dominance, but Mendel didn't realize it because he had no microscope to look inside the seed. So it's important to look at both the organismal and molecular level of genes.

What is the probability Two individuals with autosomal recessive trait will have a child with the same trait?
If they are expressing the trait, 100%, as their genotypes would be, rr X rr If they both carry the trait and it is dominated, Rr X Rr, then the probability would be, 25% of their child expressing the trait.
In a certain plant rough seeds R are dominant and smooth seeds r RECESSIVE two plants with genotype?

In pea plants are round or wrinkled seeds dominant?
In pea plants round seeds are dominant to wrinkled. So to have round seeds you either will have two dominant alleles (homozygous dominant) or one dominant and one recessive allele (heterozygous)
If a plant has round seed and the genotype Rr the ''r'' stands for what?
The little r stands for a recessive wrinkled trait.
Will an offspring show a recessive trait if only one of its parent has the gene for that trait?
A family tree is a great idea, but the science is based on probability. The probability that a recessive trait will show up in a family is 25% if both parents are carriers. In order for a recessive trait to show up in a person, he/she must inherit a copy of the recessive trait from both parents. If one parent is recessive, let's say "rr" and the other parent is a carrier, say "Rr", the probability is 50%. If both parents are recessive, the probability is 100% (rr x rr). If neither parent carries the trait the probability is 0% (RR x RR). BUT, this only tells you what MIGHT happen. We all know that the probability of having a boy is 50:50, but we all know families of all boys. So it would be interesting to see if the probability works out in your family. If you do a search on the web for "genetics" or "probability and genetics" you will get plenty of hits. vanhoeck
What is the probability that an egg cell from a female with genotype RR will contain the recessive allele?
Zero. If it's RR that means it only contains the dominant allele
