Explanation: Mendel based his experiments on pea plants and studied seven pairs of contrasting traits. Yellow seed colour is the dominant trait and green seed colour is the recessive trait.
What is the dominant trait color for peas?
When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version. Meaning all of the seeds they make will grow into pea plants with green peas.
How many of the following traits in garden pea are dominant?
Axial flower position, green pod colour and round seed shape are all dominant characters.
What is a dominant trait in plant?
Dominant traits are those that are inherited unchanged in a hybridization. Recessive traits become latent, or disappear, in the offspring of a hybridization. The recessive trait does, however, reappear in the progeny of the hybrid offspring. An example of a dominant trait is the violet-flower trait.
Do peas 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.
Are yellow or green peas 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. At the time Mendel didn’t know what a gene was or how it worked but we do now.
Which of the following is a recessive trait in garden pea plant?
green seed colour
Explanation: Mendel based his experiments on pea plants and studied seven pairs of contrasting traits. Yellow seed colour is the dominant trait and green seed colour is the recessive trait.
Which of the following characters of pea plant is dominant?
Solution : Green pod colour was a dominant character in Mendel’s garden pea experiment.
Which of the following is not a dominant trait in garden pea?
So, the correct option is ‘Pod colour – Yellow‘.
Which of the following is an example of dominant trait?
Freckles, cleft chin and dimples are all examples of a dominant trait. Having almond-shaped eyes is a dominant trait whereas having round eyes is a feature controlled by recessive alleles. The trait of detached earlobes, as opposed to attached earlobes, is dominant.
Which is a dominant trait?
dominant trait. In genetics, a trait that will appear in the offspring if one of the parents contributes it.
What is an example of dominant?
The definition of dominant is a person who is in a position of power or who is exhibiting powerful or controlling tendencies. An example of dominant is a strong and powerful CEO.
What is dominance example?
A classic example of dominance is the inheritance of seed shape in peas. Peas may be round, associated with allele R, or wrinkled, associated with allele r. In this case, three combinations of alleles (genotypes) are possible: RR, Rr, and rr.
What are the dominant and recessive characters of pea plant?
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 |
Which seed color is dominant in pea plants?
If a heterozygous yellow seeded plant is crossed with a green seeded plant, what ratio of yellow and green seeded plants could you expect in F1-generation.
What traits are dominant and recessive?
| Difference Between Recessive and Dominant Traits | |
|---|---|
| Dominant Trait | Recessive Trait |
| Examples in Humans | |
| V-shaped hairline Almond-shaped eyes Right handedness Detached earlobes Dark hair Brown eyes | Straight hairline Round eyes Left handedness Attached earlobes Blond hair, red hair Blue eyes (can also be a polygenetic trait) |
Are round peas dominant?
In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas.
Why did Mendel call the green pea trait a recessive trait?
Working with garden pea plants, Mendel found that crosses between parents that differed for one trait produced F1 offspring that all expressed one parent’s traits. The traits that were visible in the F1 generation are referred to as dominant, and traits that disappear in the F1 generation are described as recessive.
How many traits did each pea plant characteristics have?
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.
How many traits in garden pea plants selected by Mendel for the genetics experiment were recessive?
There were 7 characters of the pea plant which were selected by Mendel for the experiments. The characters which were chosen by Mendel for his study were stem height, flower colour, flower position, pod shape, pod colour, seed shape, seed colour.
Which of the following is a recessive trait?
Examples of Recessive Traits
Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits. Having round (as opposed to almond-shaped) eyes is recessive, along with inability to roll one’s tongue.
