What is the phenotype of four o’clock flower?

What is the phenotype of a flower?

The phenotype of a plant is a term used to describe observable characteristics, such as height, biomass, leaf shape and so on. We use the term phenotype in a more specific context to describe the collective expression of the genotype in conjunction with the environment on a plant’s observable characteristics.

What is the phenotype produced when a red four o’clock flower is crossed in white four o’clock flower?

A red four o’clock flower (RR) is crossed with a white four o’clock flower (WW) and the resulting F1 offspring are all pink (RW).

What is the genotype of red four o’clock flower?

A red-flowered four-o’clock (any red-flowered four-o’clock) has the genotype RR; a white-flowered four-o’clock has the genotype rr. So, this cross is RR × rr. The F1 offspring will therefore all be Rr, all pink.

What is example of phenotype?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Examples of phenotypes include height, wing length, and hair color.

What is the phenotype of RR?

The result in the heterozygous genotype (Rr) is a phenotype that is a mixture of red and white, or pink.

What is the phenotype of RR alleles?

RR x rr. You’ll note that 100% of all offspring are Rr, which is the genotype. Since the genotype for all offspring are the same, and the Rr genotype encodes a pink color, then 100% of the phenotypes will be pink (NOT red – remember that this is incomplete dominance).

What are the phenotypes of the offspring?

Eye color, hair color, pod shape, and flower position are all examples of phenotypes. In this example, it asked you to do a cross between two parents who were homozygous dominant for eye color. Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene.

What is the phenotype of heterozygous flower?

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 phenotype of a plant with the genotype WW?

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.
