Purple flowers certainly are dominant to white flowers. In nature usually dark colors will be dominant over the lighter colors.

What are two alleles for feathers color?
Purple flowers are dominant to white flowers.
In pea plants purple flowers are dominant to white flowers what is the punnet square?
It depends. If the cross is homozygous, then the punnett square will be PPXpp P P p Pp pp p Pp pp Heterozygous PpXPp P p P PP Pp p PP pp If you know how to do the geno and the phenotypes then you're all set
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?

Mendel saw purple flowers in the F generation but both purple and white flowers in the F How did this help him see that traits are inherited as discrete units?
Because the traits weren't blended resulting in pink flowers. They were still purple and white.
Is the plant with flowers homozygous or Heterozygous?
Either. It matters. Since white is dominant, the allele (saying it is T for white and t for purple) could be either TT or Tt and still come out white. If the white flower is a purebred, then it is homozygous, therefore, TT. However, the flower could be white and be heterozygous.
What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
What are two alleles for feathers color?
Purple flowers are dominant to white flowers.
In the pea plants the presence of an allele for purple flowers will mask presence of an allele for white flowers. What does that mean?
Gene responsible for purple color is dominant over white color.
If the plants has 9 purple flowers and 3 white flowers what are the factors in the parents?
The factors are purple (P) and (W) for white flowers. Since neither of the alleles were dominant it became co-dominance and the flowers had both colors
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%

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

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.
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.
What was the result when Mendel cross pollinated true breeding purple flowering plants and true breeding white flowering plants?
He got purple flowers, because purple is dominant over white, and a plant with the combination of purple and white will be purple. P being the purple gene, p being the white, Pp will be purple, just like PP. Only pp will be white.
When purple is a dominant the white offspring of purple and white parents will be?
Pp Not Pp it is pp
