What is the genotype of a white flowered snapdragon?

The genotype for the pink flower is Rr and the genotype for the white flower is rr.

What is the genotype of a white flower?

Purebred white flowers have a genotype of two white alleles, which displays the white phenotype.

What is the phenotype of a snapdragon with the genotype RR?

The RR genotype in snapdragon shows the phenotype of red flowers. The Rr genotype shows the phenotype of pink flowers and the rr genotypic character…

What is the genotype of the red snapdragon?

We are told that the genotype of red snapdragons is CR CR. The C means color and the R means red. … In these cases, the phenotype of each individual plant is its flower color, red, white, or pink. The question states that the inheritance of flower color in snapdragons shows incomplete dominance.

What are the 3 phenotypes for snapdragons?

The question tells us that there’re three potential phenotypes for this flower color trait in snapdragon plants, red flowers, white flowers, or they can have pink flowers.

What is the genotype of a heterozygous snapdragon flower?

In snapdragons, flower color is controlled by incomplete dominance. The two alleles are red (R) and white (R’). The heterozygous genotype is expressed as pink.

What is the chance to have a white flower?

Predicting Offspring Phenotypes

Only offspring with the bb genotype will have the white-flower phenotype. Therefore, in this cross, you would expect three out of four (75 percent) of the offspring to have purple flowers and one out of four (25 percent) to have white flowers.

When a red snapdragon is crossed with a white snapdragon?

Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time.

What color would the snapdragon flowers be for a heterozygous RR flower?

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

When red snapdragon flowers are crossed with white snapdragon flowers their offspring are all pink the F1 pink phenotype is a result of?

This phenomenon, called incomplete dominance, is seen when red snapdragons are crossed with white snapdragons: All the F1 hybrids have pink flowers.

What is the genotype for black chickens?

The black color is represented by allele B and white color by allele W , as neither of these allele can dominate over the other. On mating a black chicken with white chicken, the offsprings will inherit B allele from black parent and W allele from white parent. The genotype of offsprings will be BW.

When red and white flowers are crossed pink flowers are produced?

Explanation: Incomplete dominance is an example of a non-mendelian trait (doesn’t follow the genetic rules established by Gregor Mendel). When two parents mate and produce offspring, the offspring is a blend of the two parents. So, a red flower and a white flower would make a pink flower.

Is a pink snapdragon dominant?

Snapdragon also shows incomplete dominance by producing pink-colored snapdragon flowers. The cross-pollination between red and white snapdragons leads to pink color flowers because none of the alleles (white and red) is dominant.

What is the genotype of a plant with the genotype RR?

When ever the R gene is present in the genotype of a plant, the flower color is always red. The mutant form of this gene, which is recessive, is often written r. Plants with the genotype RR or Rr have red flowers.

When pure red flowered snapdragon is crossed with white flowered variety The phenotypic ratio obtained in F2 generation is?

On crossing them the F1 plants or hybrids possess pink flowers. On selfing them, F2 generation has plants in the ratio of 1 red : 2 pink : 1 white flowered plants with phenotypic ratio being same as genotypic ratio.

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).
