What is a recessive trait in pea plants?
Green seed and wrinkled seeds were recessive to yellow and round seeds; yellow, constricted pods were recessive to green and full pods. Dwarf stem and white flowers were recessive to tall stem and violet flowers.
What are the 7 dominant traits in pea plants?
Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
What is the recessive color of a pea plant’s seed coat?
Genetics Quiz

What do dominant and recessive mean?
(In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes).
What is the dominant shape of a pea pod?
The dominant shape of a pea pod is smooth. You know because the smooth trait shows up in the F1. That’s why its allele is a capital letter. The symbol for the recessive allele for pod color is c (lower-case).
Which of the following contrasting traits are dominant for pea seed?
Explore
| Trait | Dominant Expression | Recessive Expression |
|---|---|---|
| Form of ripe seed (R) | Smooth | Wrinkled |
| Color of seed albumen (Y) | Yellow | Green |
| Color of flower (P) | Purple | White |
| Form of ripe pods (I) | Inflated | Constricted |
What are dominant traits examples?
Examples of Dominant Traits
- Dark hair is dominant over blonde or red hair.
- Curly hair is dominant over straight hair.
- Baldness is a dominant trait.
- Having a widow’s peak (a V-shaped hairline) is dominant over having a straight hairline.
- Freckles, cleft chin and dimples are all examples of a dominant trait.
What is the dominant trait in a pea plant?
What is dominant trait in pea plant? Some of the contrasting traits selected were smooth or wrinkled seeds, yellow or green seeds, inflated (full) or constricted green or yellow pods and tall or dwarf plants. In these green pod is the dominant trait and the yellow pod is a recessive trait. Hence, a green pod is a dominant trait in pea.
What are the characteristics of dominant and recessive plants?
DOMINANT TRAITS: round seeds, yellow cotyledons, grey coat, full and green pods, tall RECESSIVE: wrinkled seeds, yellow cotyledons, white coat, constricted and yellow pods, dwarf Home Science Math and Arithmetic
Are yellow seedpods dominant on pea plants?
Seedpods on pea plants are either yellow or green. Yellow seedpods are genetically recessive. Green seedpods are genetically dominant. Mendel discovered that no yellow seedpods were present in the offspring of crossbred green pod and yellow pod plants.
What characteristics did Mendel look for in pea plants?
Other Characteristics Mendel studied a total of seven traits in pea plants. In addition to seedpod color, flower color and flower position, the geneticist looked at the texture of seeds, seed albumen, the length of the plant stem and the form of ripe pea pods.
