Which genotypes will produce white flowers?

You know that the genotype rr gives white flowers, and this happens in one combination, so 1/4 of the offspring will have white flowers.

What is the genotype of white?

Since there are recessive offspring, the white parent must have carried the recessive allele and therefore had the heterozygous genotype, Ww.

What are the 2 genotypes of a pea plant that produce white flowers?

Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

What is the allele for white flower color?

Ten white flowered lines carry the G allele, and seven of these have been found to carry the JI 1987 indel allele. For three white flowered lines neither mutation has been identified. (C) Flower color phenotype and alignment of SNPs at the junction between exon 6 and intron 6 of the bHLH gene of 148 pea lines.

Can a white flower be heterozygous?

Incomplete dominance means that neither color shows dominance in the hybrid generation. This means that instead of solid red or solid white flowers, the heterozygous plants will display a mixture of both colors.

What is the genotype of red and white flower?

We will label the alleles R and r, and suppose that plants with two R alleles (genotype RR) have red flowers, those with two r alleles (genotype rr) have white flowers, and those with one of each (genotype Rr) have pink flowers.

What are the 3 types of genotypes?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive).

What is the genotype of White Rose?

The mutant form of this gene, which is recessive, is often written r. Plants with the genotype RR or Rr have red flowers. Plants with the genotype rr have white flowers.

Is SS heterozygous or homozygous?

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.

What is a heterozygous genotype?

An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

What is genotype example?

A genotype is the collection of genes that all living things, including you and everyone you know, carry. … For example, if your MC1R gene leads to you having red hair, then you have the genotype for red hair. Humans are diploid organisms, which means you have two copies of each chromosome—one from each parent.

Which is a homozygous genotype?

(HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.

What would the heterozygous genotype be of a flower that is white and red if these traits were said to have incomplete dominance?

In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (W). … The two alleles are Red (R) and White (W). The heterozygous genotype is expressed as pink.

What is genotype and 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.

What is the genotype of the pink flowers?

The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink.

What is co dominant?

= Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
