So, the correct answer is ‘green pod‘.

Explore
| 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 |
What is an example of a dominant trait in pea plants?
An example of a dominant trait is the violet-flower trait. For this same characteristic (flower color), white-colored flowers are a recessive trait. The fact that the recessive trait reappeared in the F2 generation meant that the traits remained separate (not blended) in the plants of the F1 generation.
What are the 7 dominant traits in pea plants?
During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms (Figure 3). The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or winkled), pea color (green or yellow), and so on.
Do pea plants have dominant traits?
Mendel cross-bred peas with 7 pairs of pure-bred traits. First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits.
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.
Is green or yellow dominant in pea plants?
Since yellow is dominant to green, all of the offspring were yellow.
What is the recessive trait of pea plant?
The axial flower position was recessive to terminal position. Green seed and wrinkled seeds were recessive to yellow and round seeds; yellow, constricted pods were recessive to green and full pods.
What is the dominant shape of a pea pod?
Full pod shape
Full pod shape is completely dominant to constricted peapod shape. Pea plant size is also controlled by one gene-two allele system with tall size being completely dominant to dwarf size. Given a plant was heterozygous for pod shape and homozygous recessive for plant size: a.
Which of these is not a dominant trait of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
What are the 3 laws of Mendel?
The three laws of inheritance proposed by Mendel include: Law of Dominance. Law of Segregation. Law of Independent Assortment.
What is the 7 traits studied by Mendel in his garden pea?
The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.
What is 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.
Are wrinkled peas dominant or recessive?
The shape of the pea seeds is controlled by two alleles. S is dominant alleles and stands for smooth and s is recessive allele and stands for wrinkled.
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.
How did Mendel control pollination in pea plants?
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.
Is green color dominant?
Green and red colour of seeds are the recessive and dominant traits respectively.
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.
Why are peas green not yellow?
Chlorophyll is broken down by proteins encoded by so-called stay-green genes, and the decline of chlorophyll levels causes yellowing of the peas. Many plants that we eat have been selected for mutations in these genes, which thus cause retention of greenness.
Is Round green a dominant?
In pea plants, Round (R) and Yellow (Y) features of seeds are dominant over wrinkled (r) and green (y) features.
What is the difference between yellow and green peas?
Yellow and green split peas have a similar nutritional content and cooking time, but yellow peas tend to have a more earthy flavor, while green peas are sweeter. Due to their versatility, both green and yellow split peas are found in the traditional dishes of a variety of cultures.
