You asked: What would be the phenotype of the genotype RrYy?

How do you determine phenotype from genotype?

Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related.

What is the phenotype of the f1generation?

As expected from the 1st law, the F1 generation shows a uniform round yellow phenotype, since one dominant and one recessive allele was inherited from the parents.

When RrYy and RrYy are crossed in f2 generation the ratio of RrYy will be?

2 : 1 : 4 : 2.

What is the probability that RrYy RrYy would produce RrYy?

What is the probability that RrYy x RRYy would produce RrYy? Round (R) is dominant to wrinkled (r). Yellow (Y) is dominant to green (y). There is a 1/2 chance that the seeds would be round; There is a 1/2 chance that the seeds would be Yellow.

IT IS SURPRISING:  Which of the following distinguishes metaphase 1 of meiosis from metaphase of mitosis?

In which proportion RrYy genotype will produce?

1 : 2 : 2 : 4.

What is genotype phenotype?

A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

How do you determine the phenotype?

An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What is phenotype and genotype quizlet?

Genotype refers to the alleles you possess for a particular gene or set of genes. Phenotype is the physical trait itself, which may be influenced by genotype and environmental factors.

What are the predicted phenotypes for the F2 generation?

In the resulting F2 generation, 3/4 showed the dominant phenotype, and 1/4 showed the recessive phenotype. For example, when a round seed line was crossed to a wrinkled seed line, the F1 generation was all round, and the F2 generation showed a phenotypic ratio of 3 round : 1 wrinkled.

What is the phenotype of a plant with the genotype RW?

Correct! The genotype for the pink flower is RW, and the genotype for the white flower is WW. This would lead to a 50 percent chance of the offspring having a phenotype of pink.

What is the phenotype of SS?

Specifically, heterozygous (Ss) individuals express both normal and sickle hemoglobin, so they have a mixture of normal and sickle red blood cells. In most situations, individuals who are heterozygous for sickle-cell anemia are phenotypically normal. Under these circumstances, sickle-cell disease is a recessive trait.

How do you cross RrYy and RrYy?

The gametes are RY and ry. F2 generation- Self cross is done between RrYy. The number of RrYy heterozygous hybrids obtained are 4. Thus, the correct answer is option ‘A’.

What is the phenotypic ratio and genotypic ratio of F2 generation?

The normal phenotypic ratio in F2 generation is 3:1 and the genotypic ratio is 1:2:1.
