| Color of unripe pods (G) | Green | Yellow |
Which flower color is dominant in pea plant?
In the pea plant, purple colour of flower is dominant over white colour. Progeny obtained by crossing pure purple flowered plants with white flowered plants are self-pollinated.
Is yellow or green dominant in peas?
Yellow peas (I) are dominant to green peas (i). The I gene is on chromosome 1. In all pea plants, immature peas are green.
What is dominant for pea plants?
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted.
Is green dominant or recessive in peas?
Mendel’s experiments showed that green is the recessive seed color in pea plants.
Which colour is dominant white or violet?
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.
Is flower color dominant or recessive?
The recessive trait does, however, reappear in the progeny of the hybrid offspring. An example of a dominant trait is the violet-colored flower trait. For this same characteristic (flower color), white-colored flowers are a recessive trait.
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 yellow seed color dominant or recessive?
Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive.
Is green color dominant?
Green and red colour of seeds are the recessive and dominant traits respectively.
What color are peas?
A pea is a most commonly green, occasionally golden yellow, or infrequently purple pod-shaped vegetable, widely grown as a cool-season vegetable crop.
What is the dominant shape of a pea pod?
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 is the recessive trait of pea plants?
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.
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.
Which is a dominant trait that Mendel observed in pea plants?
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.
Why are peas green?
It is now known that the green colour of mature pea seeds is due to the abundance of chlorophyll (a central component of the plant photosynthetic machinery).
Is violet flower colour dominant?
Violet flower colour is dominant over white flower colour in pea plants.
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.
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Which flower Colour is due to the recessive allele?
White flowers are due to a recessive allele at a single locus. To explore the genetic architecture of this difference in flower color, we conducted classic genetic crosses between white-flowered and pink-flowered plants.
Are purple flowers dominant or recessive?
From this observation, Mendel proposed that there are two types of alleles: dominant and recessive. A dominant allele only needs to be present in one copy for the phenotype to be seen. For pea plants, the allele that determines purple flower color is dominant. A capital letter indicates a dominant allele.
