purple colour.
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.
What is the flower colour of pea plant?
The purple colour of wild type pea flowers, and flowers of many other plants, is a result of the accumulation of pigment molecules called anthocyanins. The biochemistry of their production has been studied for many years.
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 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.
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.
Which is dominant purple or white flowers?
These are the parental generation. Their offspring—the first filial, or F1, generation—each receive one purple allele and one white allele. Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele.
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 green color dominant?
Green and red colour of seeds are the recessive and dominant traits respectively.
Is green pea dominant or recessive?
Green pea seeds ( yy ) are recessive to yellow pea seeds ( YY )in the given cross. When two heterozygous pea plants ( Yy ) are crossed the offsprings will be 75% ( 3/4 ) dominant and 25% (1/4) recessive according to punnet square i.e, YY, Yy and Yy. So, if 1000 individuals are produced than 750 will be dominant.
Is yellow seed color dominant or recessive?
dominant
Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive.
Are white flowers dominant or recessive?
Answer and Explanation: According to Mendelian inheritance, the presence of even one dominant allele in the genotype will result in the expression of a dominant allele. The white colour of the flower is a recessive trait.
What is the genotype of pea plant with yellow pods?
Complete answer:
A pea plant with yellow round seeds is crossed with another plant with green wrinkled seeds. The genotype of yellow round seeds is YYRR and the genotype of green wrinkled seeds is yyrr.
Is violet flower colour dominant?
Violet flower colour is dominant over white flower colour in pea plants.
What are dominant and recessive traits in pea plants?
The following table shows each of the traits and which traits are dominant and which recessive.
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 |
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
What are the purple spring flowers called?
Lilac (Syringa vulgaris) – Lilac produces small purple flowers that grow in dense clumps on the bush. It symbolizes rebirth and is often associated with Easter. Lilacs have a fragrant scent and are often found in gardens and decorative bouquets.
What are the 7 contrasting characters of pea plant?
These traits included: flower colour (purple or white), flower position (axial or terminal), seed colour (yellow or green), seed shape (round or wrinkled), pod colour (yellow or green), pod shape (inflated or constricted), and stem length (long or short).
What is the allele for purple flowers?
In pea plants, the allele for purple flowers (W) is dominant to the allele for white flowers (w). To determine whether a plant with purple flowers is homozygous or heterozygous with respect to flower color, the plant should be crossed with another pea plant with what genotype and phenotype with respect to flower color?
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.
Why did Mendel choose pea plants?
Mendel selected pea plants for his experiments due to their easily detectable, contrasting characters. These are bisexual plants and grow to maturity in a single season only. In these plants, cross-pollination can also be done artificially.
What is the genotype of the yellow colored parent?
The dominant seed color is yellow; therefore, the parental genotypes were YY for the plants with yellow seeds and yy for the plants with green seeds.
