These plants would serve as the P1 generation for the experiment. In this case, Mendel crossed the plants with wrinkled and yellow seeds (rrYY) with plants with round, green seeds (RRyy). From his earlier monohybrid crosses, Mendel knew which traits were dominant: round and yellow.
Which of the following is a dominant trait in Mendel’s pea plants?
So, the correct answer is ‘green pod‘.
What are the dominant traits of a pea plant?
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 was dominant in Mendel’s experiment?
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 Did Mendel’s experiments with pea plants show?
Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.
How many dominant traits are present in pea plant from the given list?
Axial flower, yellow pod, flower position, pod shape, terminal flower, wrinkled seed, tall plant, white flower, seed shape.
Which of these is not a dominant trait of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Which is a dominant trait?
A dominant trait is an inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele.
What is dominant trait with respect to height in pea plant?
A cross between a tall plant (TT) and short pea plant (tt) resulted in progeny that were all tall plants because tallness is the dominant trait. Thus, tallness is the dominant trait.
Is green or yellow dominant in pea plants?
Since yellow is dominant to green, all of the offspring were yellow.
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.
What was Mendel’s conclusion from his experiments with the peas?
In 1865, Mendel presented the results of his experiments with nearly 30,000 pea plants to the local Natural History Society. He demonstrated that traits are transmitted faithfully from parents to offspring independently of other traits and in dominant and recessive patterns.
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.
What are the 7 traits of pea plants that Mendel studied?
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.
How did Mendel determine dominant and recessive traits?
Fundamental theory of heredity
Mendel found that paired pea traits were either dominant or recessive. When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate.
What was the result of Mendel’s experiment?
In 1865, Mendel presented the results of his experiments with nearly 30,000 pea plants to the local Natural History Society. He demonstrated that traits are transmitted faithfully from parents to offspring independently of other traits and in dominant and recessive patterns.
What color is dominant in pea plants?
For the seed colour, yellow is the dominant trait and green is recessive while for the fruit (pod) colour, green is dominant and yellow is recessive. Q. A monohybrid cross is conducted in which a pea plant that produces yellow coloured seeds was crossed with a pea plant that produces green coloured seeds.
What are the dominant and recessive characters of 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.
Which is dominant trait violet or white?
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.
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.
Which genes are more dominant?
And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
