the dominant shape of a pea pod is smooth. You know because the smooth trait shows up in the F1.
Is inflated pod dominant or recessive?
dominant trait
Hint: For pod shape in pea plant inflated pod shape is a dominant trait whereas constricted pod shape is a recessive trait.
What is the dominant traits of constricted pod shape?
Explore
| Trait | Dominant Expression | Recessive Expression |
|---|---|---|
| Form of ripe pods (I) | Inflated | Constricted |
| Color of unripe pods (G) | Green | Yellow |
| Position of flowers (A) | Axial | Terminal |
| Length of stem (T) | Tall | Dwarf |
What is inflated pod and constricted pod?
For pod shape in pea plant inflated pod, the shape is a dominant trait whereas constricted pod shape is a recessive trait.
Which one of these traits of pea plant is expressed only in homozygous condition?
recessive
Out of all the six traits mentioned in the question, it is only the violet petals trait that is dominant, all others are recessive. For these recessive traits to be expressed, they have to be in the homozygous condition.
Which pod colour is dominant?
Green pod colour is dominant over yellow pod colour in pea plants.
Which position of flower is dominant in pea plant?
Answer: in a pea plant axial position of flower is considered as dominant trait and terminal position of flower is considered as recessive trait. heterozygous plant with terminal flower is not possible.
Which is dominant inflated or constricted?
The trait to produce inflated pods is dominant over the constricted pods. The green colour of pod is dominant over yellow colour of pod.
What are the some dominant traits studied by Mendel in pea plant?
Out of the seven pairs of contrasting traits studied by Mendel in pea plant, round seed shape, yellow seed colour, violet flower colour, inflated pod shape, green pod colour, axial flower position and tall stem height are dominant traits.
What is a pod shape?
Oval in shape, symmetrical about the middle, i.e. like a squashed circle (e.g. Castanospermum australe).
What is the genotype of constricted pod?
A pea plant heterozygous for inflated pods (Ii) is crossed with a plant homozygous for constricted pods (ii). Draw a Punnett Square for this cross.
| Genotype | Red blood cell appearance | Phenotype (blood group) |
|---|---|---|
| IAIA or IA i | Carbohydrate A | A |
| IBIB or IBi | Carbohydrate B | B |
| IAIB | Carbohydrate A and B | AB *codominance* |
Is green seed color dominant or recessive?
recessive
Mendel’s experiments showed that green is the recessive seed color in pea plants.
What is the genotype of inflated pod?
If our unknown plant is homozygous (PP), all of the offspring will have inflated pods (genotypes Pp). If our unknown plant is heterozygous (Pp), then half of the offspring will have inflated pods (Pp) and half will have constricted pods (pp).
Which character of pea plant is not expressed in heterozygous condition?
(ii) Dominant traits cannot be expressed in heterozygous condition.
Why did Mendel choose garden pea for his experiment Class 10?
Mendel choose pea plants for his experiments because of the following reasons: (i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed.
Which of the following traits in pea plant is recessive?
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 colour is dominant 4 colour in pea?
Total four colour tested by Mendel from seven contrasting trait of garden pea. Colour of unripe pod i.e., green (dominant) yellow (recessive), colour of flower or seed coat. Coloured (dominant) like red and white (recessive).
Is green or yellow dominant in pea plants?
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.
How many dominant characteristics are present in pea plant?
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. All these characters belong to different chromosomes in the pea plant.
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
What is dominant character?
Definition. (genetics) An inherited trait that results from the expression of the dominant allele over the recessive allele. Supplement. The inheritance of one or two copies of the dominant alleles results in the expression of a dominant trait.
