What happens when a true breeding purple flower pea plant is crossed with a true breeding white flower pea plant?
You cross a “true-breeding” purple flowered, tall pea plant (PPTT) with a “true-breeding” white flowered, dwarf pea plant (pptt) and you get 100% purple, tall pea plants in your F1 generation. Both parent plants are “true breeding” and all of the F1 offspring have purple flowers and round seeds.
Could two plants with purple flowers produce a plant with white flowers?
Can two plants with purple flowers produce offspring with white flowers? Yes, if both parents are heterozygous for the trait.
Could a plant with purple flowers and one with white flowers produce purple flowered plants could they produce plants with white flowers explain for both questions?
Explanation: Let us consider a cross between two plants heterozygous for purple flowers. Each plant will produce two types of gametes, i.e. 50% gametes carrying (P) allele and 50 % carrying (p) allele. These plants will bear white flowers.
What is the genotype for flower color of a plant has two alleles for white flowers?
Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white).
What are the chances that two white flowers in pea plants would produce a purple flower pea plant?
A cross between two pea plants produces offspring in which approximately 50% of the flowers are white and 50% are purple.
When a pea plant that is heterozygous for flower color is purple and crossed with a white flowered pea plant what results do you expect to see in the offspring?
Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.
Why did the F1 generation showed all flowers to be purple rather than a mix of white and purple 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 are the possible pairs of alleles for flower Colour in a pea plant that has purple flowers?
Since the purple-flowered plant is true Since the purple flowered plant is true breeding, it has two dominant alleles. The genotype of the purple-flowered plant is PP. Since white flowers are recessive, the only possible genotype for a white-flowered plant is pp.
Is PP genotype or phenotype?
A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive).
Is PP purple or white?
This means that the gene for color is expressed in two different forms, either white or purple. The two alleles representing the trait are identical (e.g. PP for purple color, pp for white color).
What phenotype would be PP?
Predicting Offspring Phenotypes P is dominant to p, so offspring with either the PP or Pp genotype will have the purple-flower phenotype. Only offspring with the pp genotype will have the white-flower phenotype.
What is the phenotype of a plant with PP?
For example, when Gregor Mendel did his experiments with pea plants, he saw the flowers would either be purple (the dominant trait) or white (the recessive trait). A purple-flowered pea plant may have the genotype PP or Pp. A white-flowered pea plant would have the genotype pp.
How rare is having green eyes?
Only about 2 percent of the world’s population has green eyes. Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. As in blue eyes, there is no green pigment. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green.
