What else can I help you with?
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?

A cross between a white rooster and a black hen is 100 percent blue offspring when two of these offspring are mated the probable phenotypic ratio seen in their off spring would be what?
If you crossed a black hen/roo with a white hen/roo, the offspring would NOT be blue. If he was recessive white, the chicks would be black. If he was dominant white, the chicks would be white with some black "smudges" or "spots". The only way to produce 100% blue chicks is to cross a black roo over splash hens or a splash rooster over black hens.
If a female fruit fly heterozygous for red eyes crossed with a white eyed male what percent of their offspring would have white eyes?
All the offspring will have red eyes because the trait for red eyes is dominant and the female is heterozygous (carrying one dominant red eye allele). White eyes are recessive, so the offspring would need to inherit two white eye alleles to have white eyes.
If a white eyed makes fruit fly were crossed with a heterozygous red eyed female fruit fly what ratio of genotypes would be expected in the offspring?
The cross would result in a 1:1 ratio of white-eyed to red-eyed offspring. Half of the offspring would inherit the white-eyed trait from the white-eyed male, while the other half would inherit the red-eyed trait from the heterozygous red-eyed female.
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).
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.
Purple flower color is dominant over white flower color in peas. Suppose two white flowered pea plants are crossed and produce 1000 offspring. How many of those offspring would you expect to have white flowers?

How many of those offsprings would you expect to have white flowers?
If we assume complete dominance of the white flower trait and use a Punnett square for a heterozygous cross (Rr x Rr), we would expect approximately 3 out of 4 offspring (or 75%) to have white flowers and 1 out of 4 offspring (or 25%) to have red flowers.
What is the proportion of the monohybrid backcross between a red flower and a white flower?
The backcross between a heterozygous (monohybrid) red flower plant (Rr) and a homozygous recessive white flower plant (rr) would produce a ratio of 1Rr:1rr. So you would expect half of the offspring to be red (Rr) and half the offspring to be white (rr).
If you performed the Drosophila cross LL x ll what phenotypic ratio would you expect among the offspring?
You would expect a 1:1 ratio of offspring with a long body (LL) to offspring with a short body (ll) due to the incomplete dominance of the gene for body length in Drosophila.
Out of 200 offspring of heterozygous brown rabbits and white rabbits how many white rabbits would be expected?
Half of the offspring, or 100 rabbits, would be expected to be white when offspring from a heterozygous brown rabbit and a white rabbit are produced. This is due to the dominant-recessive inheritance pattern where brown is dominant and white is recessive.
If 50 DDdd pairs of parrots mate and each pair has 2 offspring how many of the 100 offspring would you expect of be Dd?

Why would a pigeon breeder select the offspring of pigeons with spotted bodies and then bread those offspring?
so the offspring will have spotted bodies
Why would pigeon breeders select the offspring of pigeons with spotted bodies and then breed those offspring's?
to produce offspring with spotted bodies
What would you expect if you breed or mate 2 different true breeding stocks of plants?
If one trait is dominant over the other, then you would expect all of the offspring to have the dominant trait.
