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
Round seeds are dominate to wrinkled seeds What percentage of the offspring will be round?
If round seeds are dominant and wrinkled seeds are recessive, then in a cross between two plants with heterozygous genotypes (Rr), 75% of the offspring will have round seeds (25% RR, 50% Rr) and 25% will have wrinkled seeds (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
What was the probability that two heterozygous parents would have an offspring that produced round seeds?
If both parents are heterozygous for seed shape (Rr), their offspring would have a 75% chance of producing round seeds (3 out of 4 possible combinations), assuming round seeds (R) are dominant over wrinkled seeds (r).
What jeans does a pea plant with wrinkled seeds have?
A pea plant with wrinkled seeds must have two recessive alleles for the wrinkled seed trait (rr). This means that both of its parents must have contributed a copy of the recessive allele for the plant to exhibit wrinkled seeds.
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.
In pea plants are round or wrinkled seeds dominant?
In pea plants, round seeds are dominant over wrinkled seeds. This means that if a pea plant has one allele for round seeds and one allele for wrinkled seeds, it will produce round seeds because the round allele is dominant.
What is the probability that two heterozygous parents would have an offspring that produced round seeds?

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.
When a plant has Two recessive alleles for wrinkled seeds how would you write the symbols for its alleles?
well it depends on the letters that you are given, recessive alleles are ALWAYS lower case.An example answer would be: ss, where s would represent the recessive allele.
In a certain plant rough seeds R are dominant and smooth seeds r RECESSIVE two plants with genotype?
rr
Round seed shape in peas is an example of a trait controlled by a dominant allele beacause?
Round seed shape in peas is an example of a trait controlled by a dominant allele because the presence of even one copy of the dominant allele results in the expression of the round seed shape phenotype. This means that individuals with either two dominant alleles (RR) or one dominant and one recessive allele (Rr) will have round seeds, while individuals with two recessive alleles (rr) will have wrinkled seeds.
