It's a genotype. The phenotype is a physical manifestation of the genotype, which means that it's what happens on the outside because an organism has the gene. An example of a phenotype would be if someone had blue eyes or something. The genotype is the two-letter abbreviation thingy.
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.
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.
Yes because if the phenotype is recessive there is only one possible genotype, little letter little letter ex. rr (wrikled pea plant seed), cc (albino), tt (short pea plant) whereas if you have a dominante phenotype there are two possible genotypes, big letter big letter or big letter little letter ex. RR Rr (round pea plant seed), CC Cc (normal skin pigmentation) TT Tt (Tall Pea plant)
Gene mutation causes the phenotype frequency in a population to change after each generation.
A punnet square is a 2x2 grid that is used to show the probability of an offspring showing a certain genotype and phenotype. The genotype is shown by using a letter for the trait. A capital letter is used to represent a dominant allele and a lowercase letter is a recessive. Ie: a heterozygous individual would be shown as having genotype Rr for a trait. If their genotype contains at least one dominant allele, then their phenotype is shown as the dominant trait. If the trait is eye color, R being dominant brown eyes, and r being recessive blue eyes, then the individual with either RR or Rr will have brown eyes. and if they have rr, then they have blue eyes. Now back to the punnet square, The top of the square will have the genotype of one parent, and the side will have another parent. If the father is RR, then each column will have a R over it. If they are Rr, then the first column will have an R and the second will have a r. Likewise, if they are recessive, then the top of the square will have rr. The same is shown on the rows on the side. The genotype goes down the two squares on the side. The genotype probability is found by crossing each allele in the boxes. If one box has R over it, and r to the right, then the box contains Rr. This is used to fill in all four boxes. In the end, If you have {RR, Rr, rr, rr} as your resulting genotypes, then there is a 50% chance that the offspring will have Dominant or recessive phenotype. The genotype ratio is then 1:2:1 and the phenotypic ratio is 2:2.

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.
dominant
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
The resulting generation will have a 1:1 ratio of RR to rr genotypes when crossing an Rr genotype with a rr genotype, as each parent will contribute one allele to the offspring.
The phenotype of an individual is ultimately determined by a combination of their genetic makeup (genotype) and environmental factors. Genes provide the instructions for building and maintaining an organism, while the environment can influence the expression of these genes. The interaction between genetics and environment shapes the physical and behavioral characteristics that make up an individual's phenotype.
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.
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.
A phenotype refers to an organism's physical characteristics or traits that result from the interaction of genetic and environmental factors. It includes attributes like height, eye color, and behavior that are observable or measurable in an organism. Phenotype is influenced by an individual's genotype, which is the specific genetic makeup of an organism.
If I'm correct in what you mean by a 2 out of 4 punett square (probability of offspring having 1 gene from 1 parent if the other parent has none of that gene) the you can get the answer with some basic statistics:P(A) * P(B) * P(C) * P(D) = P(A, B, C, and D in 4 iterations assuming independent events)A = .5B = .5(.5 * .5 * .5 * .5) = .0625 = 6.25%
Yes because if the phenotype is recessive there is only one possible genotype, little letter little letter ex. rr (wrikled pea plant seed), cc (albino), tt (short pea plant) whereas if you have a dominante phenotype there are two possible genotypes, big letter big letter or big letter little letter ex.
