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?

N an experiment with pea plants two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed The results are offspring with purple flowers 25 offspring with wh?
The results suggest that the allele for purple flowers is dominant (P) and the allele for white flowers is recessive (p). The Punnett square for the cross would show a 3:1 ratio of purple to white flowered offspring, as predicted by Mendel's laws of inheritance. This indicates that the purple flower trait is dominant and the white flower trait is recessive.
What crosses would give 100 of the purple flowers phenotype but also would allow you to set the white flower phenotype in the following generation?
To achieve 100 purple flower phenotypes while also allowing for white flower phenotypes in the next generation, you can cross a homozygous purple flower plant (PP) with a heterozygous purple flower plant (Pp). This will yield 50% PP and 50% Pp offspring, all displaying the purple phenotype. To introduce white flowers in the next generation, you can then cross the heterozygous offspring (Pp) among themselves, producing a 25% chance of white flowers (pp) in the subsequent generation.
Purple flowers are dominant to white flowers?
If purple flowers are dominant to white flowers, it means that a plant with one purple allele and one white allele will display the purple flower phenotype. The white flower phenotype would only be expressed if the plant inherits two white alleles.
When gregor mendel crossed true breeding purple flowered plants with true breeding white flowered plants all of the offspring were purple because?
purple is dominant over white in Mendel's pea plant experiment, meaning that the offspring inherited at least one purple allele from the purple parent. This resulted in all the offspring showing the purple trait.

In pea plants purple flowers are dominant to white flowers if two white flowered plants are cross what percentage offspring will be white folwered?
75%
What percentage of their offspring will have purple flowers?
The answer depends on whose offsprings. And since you cannot be bothered to provide that information, I cannot provide a sensible answer.
A pansy homozygous for purple flowers is crossed with a pansy homozygous for pink flowers. Which genotypes will be exhibited in the offspring?
If the flowers are something like PP (purple) and pp (pink), then the flowers will be Pp if you do the traditional square used in most high school classes.
Two true-breeding pea plants are crossed one with purple flowers and the other with white. Their offspring are?
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.
What is the probability of obtaining a purple-flowered offspring?
None if the flowers are daffodils! They can only be yellow or white.

A cross between homozygous purple flowered and homozygous white flowered pea plants results in offspring with purple flowers This demonstrates?
The principle of dominance.The gene for purple flowers is dominant, while the gene for white flowers is recessive. We know this because both flowers are homozygous, meaning their genes are the same. The genotype of Penelope (the purple flower) is PP, or purple purple. The genotype of Walter (the white flower) is pp, or white white. Because of this, if the gene for white petals was dominant, all the flower offspring would display white petals. If the genes were codominant, the flower offspring would be lavender, an even mix between the white and purple phenotypes.The Punnet square for this example (if you are a visual person) looks like this:......................Walter........................p | p....................___ | ___................P | Pp | Pp |Penelope .....________................P | Pp | Pp |...................|___|___ |You can clearly see that all the offspring are heterozygous, yet because they all share Penelope's phenotype, it is quite obvious that, again, the gene for purple flowers is dominant.
If purple flower color is dominant over white flowers color how can two purple flowered parents produce white flowered offspring?
It can happen when both parents are a heterozygous
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 an experiment with pea plants two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed The results are offspring with purple flowers 25 offspring with w?
they are fine; expected ratios might not been seen simply due to chance
What was the first generation offspring in Mendel's experiment?
3 purple flowers and 1 white flower the ratio is 3:1 ur welcome! hahaha
