What else can I help you with?
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.
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
What were the results of Mendel's first experiment?
i believe his results were that after cross pollinating to non-purebred pea plants, the offspring were all tall like the female,and when he crossed the other two, he received three tall pea plants and one short
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.
Is white the color of the eggplant flower?
White & Purple :)
How do you determine the genotype of a purple-flowering plant?
by crossing a purple flower and a white flower,it also counts on the darkness of the flower
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.
There are two alternate flower colors the pea plant they are purple and white purple is dominant over white purple and white are called what?
A grape, A purple sun, A purple cloud and A purple Teddy!
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.
What colors do the Jacaranda flower has?
Purple, blue and white
What other colours does the jacaranda flower have purple blue white or pink?
White
