Could a plant with purple flowers and one with white flowers produce purple flowered plants could they produce plants with white flowers?
Mendel discovered that by crossing true-breeding white flower and true-breeding purple flower plants, the result was a hybrid offspring. Rather than being a mix of the two colors, the offspring was purple flowered. The resulting hybrids in the F1 generation all had violet flowers.
What is the probability in percent of the two purple flowers having offspring that have white flowers?
Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. This means that 75% of the offspring displayed the dominant phenotype of purple flowers, and 25% displayed the recessive phenotype of white flowers.
When can two purple flowers produce flowers that are white?
Can two plants with purple flowers produce offspring with white flowers? Yes, if both parents are heterozygous for the trait. You just studied 36 terms!
How can two purple flowers produce a white flower?
The way the trait appears is its phenotype. In pea plants, purebred purple flowers have a genotype with two purple alleles, which produces a phenotype of purple petals. Purebred white flowers have a genotype of two white alleles, which displays the white phenotype.
How can two parent purple flowers have white flower offspring?
Only offspring with the bb genotype will have the white-flower phenotype. Therefore, in this cross, you would expect three out of four (75 percent) of the offspring to have purple flowers and one out of four (25 percent) to have white flowers.
What is the phenotype for purple flowers are dominant to white flowers?
Could two white flowers produce plants with purple flowers?
Can two plants with purple flowers produce offspring with white flowers? Yes, if both parents are heterozygous for the trait.
Is PP white or purple?
the allele P (purple) is dominant. this means that if there are one or more alleles present in the genotype of the offspring (Pp or PP), the flower will be purple. the flower can only be white if there are two recessive genes – if the flower were white, the genotype would have to be pp.
Are purple flowers dominant over white flowers?
