What is the genotype of the purple and white flower in the P generation?
The F1 plants all have one purple allele (P) and one white allele (p). The genotype is the alleles for each gene in the plant. Here the genotype is Pp.
What is the genotype of a purple flowered pea plant?
A pea plant with purple flowers could have a genotype of either PP or Pp. A pea plant with white flowers could only have a genotype of pp. As long as at least one dominant allele is g present, the plant will always have a phenotype of purple flowers.
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.
Can two plants with purple flowers produce offspring with white flowers quizlet?
Can two plants with purple flowers produce offspring with white flowers? Yes, if both parents are heterozygous for the trait.
How many generations of plants did Mendel study traits in during his experiments?
What is Gregor Mendel’s experiment?
Taking seed color as an example, Mendel showed that when a true-breeding yellow pea and a true-breeding green pea were cross-bred their offspring always produced yellow seeds….Gregor Mendel.

How many true breeding pea plant varieties did?
Which one of the following is a recessive trait in garden pea?
The axial flower position was recessive to the terminal position; green seed colour was recessive to yellow colour; yellow pod colour was recessive to green and wrinkled seed shape was recessive to round shape. The correct answer is B.
What is recessive trait?
A recessive trait is the weak, unexpressed trait of a dichotomous pair of alleles (dominant-recessive) that has no effect in the phenotype of heterozygous individuals.
Are short stems dominant or recessive?
an organism that has two different alleles for a trait. for example, the F1 plant had one allele for tall stems and one allele for short stem. all the F1 plants were tall because the dominant tall allele masks the recessive allele for short stems.
Is tall stature dominant or recessive?
For example, the gene for having an extra finger is actually dominant, while the gene for having a tall stature is a recessive trait.
Why is a pea plant that is a hybrid for stem height tall?
Hybrid pea plant is stem height tall because it has one dominant and one recessive allele. In situation like this, dominant allele covers up recessive allele for short stems.
What does it mean for an allele to be dominant or recessive?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
How do you know if a pedigree is recessive or dominant?
If both parents do not have the trait and the child does, it is recessive. If one parent has the trait and the child does or does not, it is dominant.
