Seedpods on pea plants are either yellow or green. Yellow seedpods are genetically recessive. Green seedpods are genetically dominant.
Which pea trait is dominant?
Green pod color
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted.
Is green pea recessive or dominant?
Mendel’s experiments showed that green is the recessive seed color in pea plants.
Is tall or short pea plant dominant?
tall plants
In pea plants, tall plants are dominant over short plants. If two heterozygous tall plants are crossed, what percent of the offspring will be short? In pea plants, tall plants are dominant over short plants.
Is a smooth pea dominant?
In pea plants, smooth seeds (S) are dominant to wrinkled seeds (s). In a genetic cross of two plants that are heterozygous for the seed shape trait, the Punnett square is drawn below.
Why yellow pea is dominant?
Since they were all yellow, this means that yellow is dominant over green. Having one Y is enough to mask the y and cause the peas to be yellow. The one yellow dominates the recessive green.
Which colour of pea flower is dominant?
Purple White

Trait | Dominant Expression | Recessive Expression |
---|---|---|
Color of seed albumen (Y) | Yellow | Green |
Color of flower (P) | Purple | White |
Form of ripe pods (I) | Inflated | Constricted |
Color of unripe pods (G) | Green | Yellow |
Is yellow or green seeds dominant?
Yellow colour is dominant over green and round seed shape over wrinkled seed shape.
Is hybrid dominant or recessive?
A hybrid is called heterozygous, as it has two different alleles. The offspring from a pure tall pea plant, cross-pollinated with a pure short pea plant, will result in a heterozygous plant for tallness. No organism has all dominant or all recessive genes.

Is yellow seed color dominant or recessive?
dominant
Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive. When true-breeding plants were cross-fertilized, in which one parent had yellow seeds and one had green seeds, all of the F1 hybrid offspring had yellow seeds.
What is the phenotype of TT?
tall plant
As the given genotype is Tt , it’s a heterozygous condition and in heterozygous condition the dominant trait (T – tall) will express itself. Hence, the phenotype of Tt will be a tall plant.
Which phenotype is dominant?
A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
What is the phenotype of RR?
A phenotype is a description of what an organism looks like based on its genotype. A person with the Rr genotype for tongue rolling would be able to roll his or her tongue, because he or she has the dominant allele that allows tongue rolling. So “tongue rolling” is his or her phenotype.
Why Mendel use pea plants?
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: Presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.
Why does Mendel choose pea plant?
Mendel selected pea plants for his experiments due to their easily detectable, contrasting characters. These are bisexual plants and grow to maturity in a single season only. In these plants, cross-pollination can also be done artificially.
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Why are peas green not yellow?
It is now known that the green colour of mature pea seeds is due to the abundance of chlorophyll (a central component of the plant photosynthetic machinery).
Is P generation always homozygous?
The P generation organisms are homozygous for the given trait. However, each parent possesses different alleles for that particular trait.
Are white flowers dominant or recessive?
Answer and Explanation: According to Mendelian inheritance, the presence of even one dominant allele in the genotype will result in the expression of a dominant allele. The white colour of the flower is a recessive trait.
Which colour is dominant white or violet?
Pure lines of violet-flowered plant and white-flowered plant were crossed (cross I). In another cross (cross II), the obtained progeny was crossed with the parent plant bearing white flowers.
What is the color of pea?
A pea is a most commonly green, occasionally golden yellow, or infrequently purple pod-shaped vegetable, widely grown as a cool-season vegetable crop.
