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.
In pea plants the presence of an allele for purple flowers will mask presence?
In pea plants, the presence of an allele for purple flowers is dominant over the allele for white flowers. This means that if a plant has at least one allele for purple flowers, it will exhibit purple flowers, masking the effect of the recessive white flower allele. As a result, only plants with two recessive alleles will display white flowers. This illustrates the principles of Mendelian inheritance and dominance.
In pea plants individuals that are Pp for the allele that code?
In pea plants, individuals that are heterozygous (Pp) for a particular allele exhibit a phenotype influenced by both the dominant (P) and recessive (p) alleles. The dominant allele typically masks the effect of the recessive allele, resulting in the dominant trait being expressed. For example, if P represents purple flowers and p represents white flowers, Pp plants will display purple flowers. This demonstrates the principles of Mendelian inheritance where dominant traits prevail in heterozygous conditions.

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 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.
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 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.

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.
When Gregor Mendel crossed true breeding purple flowered plants with true breeding white flowered plants all the offspring were purple because?
PP X ww or Pw X ww Because all Purple flower plants are dominant and express the color purple. This can be seen in a homozygous cross, or a heterozygous cross, ( shown above ) White plants, to breed true, must be in homozygous condition.
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.
