## What happens when you cross 2 pink flowers?

Since neither allele is dominant, they are both expressed and produces the pink variety. To get the most pink flowers, a red and white rose plant must be mated. … In this cross, all of the offspring would inherit one red allele and one white allele-RW and would be 100 percent pink!

## When pink flower 4 o’clock plant is crossed with a red flower plant what is the probability of red flower plant?

The offspring are Since plants have pink flowers and plants have red flowers, the ratio is 1 pink: 1 red. Hence, the answer is option (d) 1 red: 1 pink.

## When red 4 o’clock flowers are crossed with white 4 o’clock flowers pink flowers result What does this show?

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 probability of pink flowers if pink flowers are bred with red flowers?

In this case, if two pink-flowered pea plants are mated (“crossed” is a better word than “mated” for plants), the offspring plants are independent of each other, and each has red flowers with probability 1/4, pink flowers with probability 1/2, and white flowers with probability 1/4.

## What is the probability of having offspring with 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.

## When a pure red flowered four o’clock plant is crossed with a pure white flowered four o’clock plant what is being produced?

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).

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

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.

## 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 gene combinations do pink four o’clock flowers have?

In four-o-clocks, pink flowers are the result of a red allele and a white allele for the color gene.
