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

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

What are two alleles for feathers color?
Purple flowers are dominant to white flowers.
In pea plants individuals that are pp for the alleles that code for flower color will have purple flowers what is the phenotypes?
In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. What is the phenotype?
What percentage of the offspring will have purple flowers?
the tall plants will turn purple. it may be cool or look like pooh

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.
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%
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
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.
In pea plants individuals that are Pp for the alleles that code for flower color will have purple flowers What is the phenotype?
Pp, where P represents the dominant allele and p represents the recessive allele.
What are two alleles for feathers color?
Purple flowers are dominant to white flowers.
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 you want to know the genotype of a pea plant that has purple flowers would you use a punnet square?
No, you would use a testcross.
What is in the pea plants individuals that are Pp for the alleles that code for flower color will have purple flowers.?
A+ purple flowers.
