Your question: Is PP genotype or phenotype?

other possible genotypes of the offspring are PP and 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.

Is PP a phenotype?

Relation between the phenotype and the genotype

If we mate an homozygous bull with two horned alleles (pp) with an homozygous cow with two polled alleles (PP), the calf will be heterozygous Pp and its phenotype will be polled. Hence we have three genotypes (pp, PP and Pp) but we only saw two phenotypes.

What is the phenotype of a plant with a genotype 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.

What does the genotype pp mean?

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 PP purple or white?

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.

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.

Which flower color is recessive?

Explore

Trait Dominant Expression Recessive Expression
Color of flower (P) Purple White
Form of ripe pods (I) Inflated Constricted
Color of unripe pods (G) Green Yellow
Position of flowers (A) Axial Terminal

Is AA homozygous or heterozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

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.
