If smooth peas are dominant over wrinkled peas, it means that when a plant with one smooth pea allele and one wrinkled pea allele reproduces, all of its offspring will have smooth peas. This is because the dominant allele (smooth) masks the expression of the recessive allele (wrinkled) in the offspring's phenotype.
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
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.
Mendel's experiments showed the characteristics of genes that express complete dominance--that is, traits where one allele is completely dominant over another, and the recessive allele does not appear in the phenotype at all. Some of the specific traits that Mendel was testing include pea color (yellow or green, with green being completely dominant) pea surface texture (wrinkled or smooth, with smooth being dominant) and flower color (pink and white, with pink being dominant.)
dominant and recessive genes. to research this, he used peas and investigated the genes which determined whether a pea would be wrinkled or smooth. he was actually a mathematician and he spend ages cross breading wrinkley with straight and counting out the two different types of pea. he counted 1000 peas. approximately 250 were wrinkled and 750 were smooth, leading him to the theory that the gene for smooth pease was dominant eg. wrinkled = w smooth = W W + w = smooth W + W = smooth w + W = smooth w + w = wrinkled the 3:1 ratio hope this helps ;)
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D
Wrinkled peas are recessive, smooth peas are dominant.
If smooth peas are dominant over wrinkled peas, it means that when a plant with one smooth pea allele and one wrinkled pea allele reproduces, all of its offspring will have smooth peas. This is because the dominant allele (smooth) masks the expression of the recessive allele (wrinkled) in the offspring's phenotype.
Wrinkled seeds are recessive The F1generation carried recessive alleles.
The genotype of the offspring would be TtRr, representing that each parent contributed one dominant and one recessive allele for each gene.
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).
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.
To determine the probability of offspring having wrinkled seeds, we need to know the genetic makeup of the parents. If we assume that wrinkled seeds are a recessive trait (represented by "r") and smooth seeds are dominant (represented by "R"), then the probability depends on the genotypes of the parents. For example, if both parents are heterozygous (Rr), there is a 25% chance that the offspring will inherit the wrinkled seed trait (rr). Without specific parental genotypes, we cannot provide an exact probability.
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
Scientists use uppercase letters to represent dominant genes and lowercase letters to represent recessive genes. For example, "R" might represent a dominant gene for round seeds, while "r" might represent a recessive gene for wrinkled seeds.
if "R"= red and I assume non dominat color is white then "r"-white if "S"= smooth seed and "s"- wrinkled Your plant would be "Rrss" = Red flowers, but produces wrinkled seeds
