What trait in pea plants is being studied in the cross shown above? The trait that is being studied is the height of the pea plants.
What are the dominant traits in pea plants?
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 type of traits did Mendel cross with his plants?
Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).
What were the characteristics of the two pea plants that he crossed first?
Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.
What is a recessive trait in peas?
Mendel’s experiments showed that green is the recessive seed color in pea plants.
Which traits are dominant and recessive in pea plant?
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted. Inflated pod traits are dominant.
What is recessive and dominant trait?
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. If one of the alleles is dominant, then the associated characteristic is less likely to manifest.
What are the 7 traits Mendel studied on pea plants?
The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.
What happened when Mendel crossed a round seed with a wrinkled?
As a result of crossing these two pea variants, Mendel discovered that the round-seeded and wrinkled-seeded traits were two facets of the same character, suggesting to modern plant scientists that a single gene determines whether seeds are round or wrinkled.
Why did Mendel choose pea plant for his experiments give 4 reasons?
(i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iii) The different physical characteristics were easy to recognize and study. (iv) They have a shorter life span and are the plants that are easier to maintain.
What happened when Mendel crossed two traits pea plants?
For monohybrid cross, Mendel began with a pair of pea plants with two contrasting traits i.e., one tall and another dwarf. The cross-pollination of tall and dwarf plants resulted in tall plants. All the hybrid plants were tall.
What happens when pea plants showing two different characteristics?
When pea plants with round and green seeds are crossed with wrinkled and yellow seed (both pure line), FI generation plants have round and yellow seed.
What happened when Mendel crossed the hybrid generation plants?
Mendel noted that hybridizing true-breeding (P generation) plants gave rise to an F1 generation that showed only one trait of a characteristic. For example, a true-breeding purple-flowering plant crossed with a true-breeding white-flowering plant always gave rise to purple-flowered hybrid plants.
What Did Mendel’s cross pollination of pea plants prove?
Answer and Explanation: Mendel’s cross-pollination of pea plants proved that genes of two separate organisms are passed to their offspring.
Which of the peas traits yellow or green is dominant?
Green (Y) is dominant over yellow (y) in peas, and the smooth allele (W) is dominant over wrinkled (w). Which of the following crosses produces green and smooth peas?
How many traits did each pea plant characteristics have?
Mendel studied the inheritance of seven different features in peas, including height, flower color, seed color, and seed shape. To do so, he first established pea lines with two different forms of a feature, such as tall vs. short height.
How many of the following are recessive traits in a pea plant?
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. Thus, the correct answer is option C.
Which of the following is the example of recessive traits?
Examples of Recessive Traits
For example, having a straight hairline is recessive, while having a widow’s peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.
Which of the following is dominant trait chosen by Mendel?
The axial position was dominant to terminal flower position; green pod colour was dominant to yellow, tall plant was dominant to dwarf one and inflated pod was dominant to constricted one. Correct answer is C.
What is a dominant trait example?
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.
Which is a dominant trait?
In genetics, a trait that will appear in the offspring if one of the parents contributes it. (Compare recessive trait.)
