What is the phenotype of a pea plant that is PP for flower color?
purple color
The two alleles representing the trait are different (e.g. Pp for purple color). Although the pea plant appears purple in color (its phenotype is purple), its genotype (genetic make-up) is a mixture of a dominant “P” and a recessive ‘p” trait.
What color flowers would be produced if a plant was genotype PP?
purple
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 PP pea flower explain why a PP is the same color?
The cross between PP (purple flowers) and pp (white flowers) will produce pea plant having purple flowers having genotype Pp. P would be a dominant trait and p is a recessive trait, therefore plants having Pp genotype would be of purple colored.
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.
How would you describe genotype PP?
A genotype is the actual genetic composition or makeup of an organism. Most genes are made up of two or more different alleles, or forms of a trait. A purple-flowered pea plant may have the genotype PP or Pp. A white-flowered pea plant would have the genotype pp.
Is the allele for purple flower color dominant in pea plants?
In pea plants, the allele for purple flower color is dominant to the allele for white flower color. If you were to perform a test cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous?
How to determine the genotype of a pea plant?
Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms. white flowers and short stems. In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p).
What should the phenotypic ratio of purple flowered plants be?
If you were to perform a test cross to determine the genotype of a purple-flowered plant, what would you expect the phenotypic ratio of purple-flowered to white-flowered progeny to be if the plant is homozygous? And what would you expect if the plant is heterozygous?
How are stem length and color of pea plants controlled?
Complete the predictions using the correct terms. In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is controlled by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently.
