If a homozygous red flower is crossed with a white flower what percentage of their offspring will red have?

Assuming that white is recessive to red in this case, then the off spring would all be red but they would be heterozygous red (Rr).

∙ 15y agoCrossing two pink flowers (1/2 red 1/2 white) would result in a 25% chance of a white flower, 25% chance of a red flower, and 50% of another pink flower.
This is shown:
You started with a full red (RR) and a full white (WW) flowers.
__W W R RW RW
R RW RW
The F1 (first generation of the cross between the red and white) will give you a 100% chance of a pink flower.
So now you cross two pinks (RW)
___R W R RR RW
W RW WW Again, 25% red, 25% white, and 50% pink.
All offspring will be heterozygous for the flower color gene, with a genotype of Rr. This means that 100% of the offspring will have red flowers, as the red allele is dominant over white.

A pansy homozygous for purple flowers is crossed with a pansy homozygous for pink flowers. Which genotypes will be exhibited in the offspring?
All offspring will have the genotype for purple flowers. The offspring will be heterozygous for flower color (Pp).
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
The possible genotypes of the offspring are Bb (heterozygous blue) and bb (white). The possible phenotypes are blue and white flowers. Each offspring will inherit one allele from each parent, resulting in a 50% chance of being blue (Bb) and 50% chance of being white (bb).
In Purple flower color dominant over white flower color peas. Suppose two white flowered pea plants are crossed and produce 1000 offspring. How many of those offspring would you expect to have whit?
1000
When a cross between a red flower and a white flower yeilds pink offspring the trait is?
Incomplete dominance, where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.
A pansy homozygous for purple flowers is crossed with a pansy homozygous for pink flowers. Which genotypes will be exhibited in the offspring?
All offspring will have the genotype for purple flowers. The offspring will be heterozygous for flower color (Pp).
Suppose two white flowered pea plants are crossed and produce 1000 offspring how many of those offspring would you expect to have white flowers?
If both parent plants are white-flowered, then all of the 1000 offspring would be expected to have white flowers. This is because the white flower trait is a result of a homozygous genotype, and both parents would pass on the white flower allele to their offspring.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
The possible genotypes of the offspring are Bb (heterozygous blue) and bb (white). The possible phenotypes are blue and white flowers. Each offspring will inherit one allele from each parent, resulting in a 50% chance of being blue (Bb) and 50% chance of being white (bb).
A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers This demonstrates?
A homozygous purple flower and a homozygous white flower having offspring that are purple is an example of dominance. Traits that yield to other traits is referred to as recessive. So in this case Purple was the dominant trait and White was the recessive trait.
In Purple flower color dominant over white flower color peas. Suppose two white flowered pea plants are crossed and produce 1000 offspring. How many of those offspring would you expect to have whit?
1000
How many alleles influence a phenotype in incomplete dominance?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
In pea plants purple flowers are dominant over white flowers. Two plants both heterozygous for the gene that controls flower color are crossed. What percentage of their offspring will have purple flow?

When the phenotype of two alleles are blended what are they called?
The blending of the phenotype of the parents in the offspring is known as incomplete. colors of flowers can show incomplete dominance if a red flower is crossed with a white flower and their offspring are pink.
How is a snap dragon an example of incomplete dominance?
When they don't have pink as their color so the "parents" had to of been either both white or both pink. That is how you can tell when snapdragons are not following the pattern of complete dominance.
