It depends on the parents' genes. If both parent have a Pp genotype, then the offspring has a 25% chance of having a PP genotype. But if both parents have a PP genotype then its 100%.

A testcross on a tall pea plant produces only tall offspring. What is the genotype of the tall pea plant?
Tt
When Mendel crossed purebred purple flowering plants PP with purebred white flowering plants pp what were the flower colors of the resulting offspring?
Let us assume that both Rr and rr produce red flowers and only rr produces white flowers. Since one parents and the offspring are white, they have rr as genotypes. In order to achieve this result, the other parent would have to haev at least one r in its genotype. Since the otehr parent is red and needs to have one r, it's genotype is Rr. In short, the parents's genotypes are Rr for the red one and rr for the white one.
When purple is a dominant the white offspring of purple and white parents will be?
Pp Not Pp it is pp
What does p2 represent in the Hardy-Weinberg equation?
The Hardy-Weinberg Equilibrium equation: p2 + 2pq + q2 = 1 p is frequency of dominant allele A q is frequency of recessive allele a p + q always equals 1 pp or p2 is probability of AA occurring qq or q2 is probability of AA occurring 2pq is probability of Aa occurring (pq is probability of Aa, qp is probability of aA, so 2pq is probability of all heterozygotes Aa) These add up to 1 because they represent all possibilities. The frequency of the homozygous recessive genotype
What is the genotype of a pea plant that is true-breeding for purple flowers?
The answer is all of the produced flowers would be Pp
If you cross a while flower with the genotype pp with a purple flower with the genotype pp the possible genotypes in the offspring will be what for the cross what would the phenotypes be?
half white and half purple
If both heterozygous parents are carriers of a recessive allele for phenylketonuria the probability that a given child of these parents will have PKU is?
Pp x Pp yields PP, Pp, Pp, pp. PP is the only genotype which will cause the phenotypic expression of the gene - symptoms of PKU. Therefore the probability is 1/4 or 25%
What genotype is Pp?
pp
How else can the genotype Pp be written?
PP

When purple is a dominant the white offspring of purple and white parents will be?
Pp Not Pp it is pp
Why do the genotype Pp and pP all have the same phenotype?
because they all have at least one dominant alleles.
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 is the genotype of a pea plant that shows the recessive phenotype?
Pp
What does p2 represent in the Hardy-Weinberg equation?
The Hardy-Weinberg Equilibrium equation: p2 + 2pq + q2 = 1 p is frequency of dominant allele A q is frequency of recessive allele a p + q always equals 1 pp or p2 is probability of AA occurring qq or q2 is probability of AA occurring 2pq is probability of Aa occurring (pq is probability of Aa, qp is probability of aA, so 2pq is probability of all heterozygotes Aa) These add up to 1 because they represent all possibilities.

What is the genotype of the purple plant?
The genotype for a purple plant would be 'PP.' This will depend on whether both parents showed that phenotype, but purple is generally dominant.
