What is the genotype of a yellow seed?

YY is the homozygous dominant genotype (2 Y alleles). The phenotype of this genotype is yellow seed color. Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color.

What is genotype of seed?

The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both the physically visible and the non-expressed alleles, is called its genotype. … Seed color is governed by a single gene with two alleles.

Is green seed genotype?

Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive. … The genotype is often written as YY or yy, for which each letter represents one of the two alleles in the genotype.

Is yellow a genotype or phenotype?

Therefore, YY is the homozygous dominant genotype (2 Y alleles). The phenotype of this genotype is yellow seed color.

What is genotype example?

Genotype examples

A gene encodes eye color. … If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes, they must be homozygous for the blue eye allele.

What is the genotype of the heterozygote?

Listen to pronunciation. (HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

Why is the heterozygous pea yellow?

That means that if one allele in the genotype contains yellow, then the plant will have yellow peas. The next information given to us is that the first parent is heterozygous yellow. Heterozygous indicates that this parent has both alleles for the gene.

Are yellow seeds dominant or recessive?

Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive. When true-breeding plants were cross-fertilized, in which one parent had yellow seeds and one had green seeds, all of the F1 hybrid offspring had yellow seeds.

What is the F1 genotype?

A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus. … The offspring of the RRYY x rryy cross, which is called the F1 generation, were all heterozygous plants with round, yellow seeds and the genotype RrYy.

Is yellow pod dominant?

In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait.

Why is yellow seed dominant?

When the first crossover takes place between YY (yellow color allele) and yy (green color allele), the first $F_1$ generation produces heterozygous alleles (Yy). In which yellow is dominated, pea plants will produce yellow seeds.

Is PP genotype or phenotype?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).

What is the genotype of RR?

The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.

What are the genotypes of F1 and F2 progeny?

Homozygous tall and heterozygous tall will be in the ratio of 2:1. Thus in monohybrid cross F1 plants have similar genotype. All are heterozygous tall (Tt). In F2 generation genotypic ratio will be 1:2:1. , i.e. 1 homozygous tall: 2 heterozygous tall: 1 homozygous dwarf.
