What color are homozygous dominant 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).

What color flower is dominant?

Explore

Trait Dominant Expression Recessive Expression
Color of seed albumen (Y) Yellow Green
Color of flower (P) Purple White
Form of ripe pods (I) Inflated Constricted
Color of unripe pods (G) Green Yellow

What does homozygous dominant look like?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. 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.

Are white flowers homozygous?

In addition, the white flower is homozygous for the recessive white allele (pp).

Is flower color a dominant trait?

An example of a dominant trait is the violet-colored flower trait. For this same characteristic (flower color), white-colored flowers are a recessive trait.

Which is dominant purple or white flower?

Their offspring—the first filial, or F1, generation—each receive one purple allele and one white allele. Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. Now let’s cross the F1 flowers to create the second filial, or F2, generation.

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.

How do you know if its homozygous or heterozygous?

Because an organism has two sets of chromosomes, it usually only has two options to choose from when determining phenotype. If an organism has identical genes on both chromosomes, it is said to be homozygous. If the organism has two different alleles of the gene it is said to be heterozygous.

What does heterozygous look like?

If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.

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.

Are purple flowers heterozygous?

A plant with two different alleles is heterozygous. The characteristic that we see with our eyes is the phenotype. For Pp, the phenotype is purple flowers. … The F2 generation is 25% PP (homozygous dominant, purple flowers), 50% Pp (heterozygous, purple flowers), and 25% pp (homozygous recessive, white flowers).

What is the genotype of pink flower?

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.

Is the plant with white flowers homozygous or heterozygous?

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).

What is the genotype of white red and pink flowers?

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.

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.
