What phenotype is possible for PP?

The combinations PP, Pp, and pP have the same phenotype-purple flowers. This is because each contains at least one dominant allele (P). Only one combination, pp, produces plants that have white flowers.

What phenotypes are possible?

The phenotype is the physical manifestation of an organism’s allellic combination (genotype). For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible.

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.

What is the flower phenotype for a pea plant with the genotype PP?

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. As you can see, all of the offspring in Mendel’s first cross had a genotype of Pp. That’s why all of the plants in the p first generation had purple flowers.

What are 3 examples of phenotypes?

Phenotype Examples

  • Eye color.
  • Hair color.
  • Height.
  • Sound of your voice.
  • Certain types of disease.
  • Size of a bird’s beak.
  • Length of a fox’s tail.

What is phenotype example?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Is Black genotype or phenotype?

The appearance of an animal (or any other form of life) is considered its phenotype (think ph = physical). An animal’s genotype is its genetic make-up (think gen = genetic). Black is the phenotype of a calf with at least one black (B) allele. Red is the phenotype of a calf with two red (bb) alleles.

Is HH purebred?

Hint: BB, hh, ZZ, and jj are all examples of purebred genotypes. … Heterozygous genotypes have one copy each of the dominant and recessive allele.

What is the genotype for PP?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive).

Is PP dominant?

Explanation: The genotypes for the two plants in question can be written as PP for the homozygous dominant plant, and Pp for the heterozygous plant. Remember that a white flower can only be created if it receives two recessive alleles, one from each parent.
