In pea plants, purple flowers are dominant over white flowers. Two plants, both heterozygous for the gene that controls flower color, are crossed.
Are purple pea flowers dominant?
Pea plant flowers are either white or purple. Through breeding of multiple generations of pea plants, Mendel discovered that purple flowers are dominant and white flowers are recessive.
Why are my pea flowers purple?
Anthocyanins. Anthocyanins are red-purple pigments that can be found in many plants; for example, they are responsible for the red colour of apple skins and red wine. The purple colour of pea flowers can also be attributed to the accumulation of anthocyanins, whereas the white pea flowers lack these pigments.
Is white or purple dominant in pea plants?
Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. Now let’s cross the F1 flowers to create the second filial, or F2, generation.
What color is dominant in pea flowers?
In pea plants, purple flower color is dominant to white flower color.
Is pea color determined by a single gene?
The results of these experiments showed that pea color is controlled by one gene, which has a “green” form and a “yellow” form. Each form is called an allele.
Why is the purple flower dominant?
Purple flowers are dominant, so two P alleles or one P and one p alleles are needed for purple flowers. Green pea pods are also dominant, meaning that two GG alleles are needed or one G and one g. Thus, the genotypes that could express this particular phenotype are PPGG, PPGg, PpGG, or PpGg.
What type of pea has purple flowers?
Native pea varieties
Perhaps the most commonly grown of the native peas is the purple-flowered climber Hardenbergia. The best planting of Hardenbergia I ever saw was in Perth.
What are the traits for pea flower color?
|Trait||Dominant Expression||Recessive Expression|
|Color of flower (P)||Purple||White|
|Form of ripe pods (I)||Inflated||Constricted|
|Color of unripe pods (G)||Green||Yellow|
|Position of flowers (A)||Axial||Terminal|
What color is a pea plant flower?
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.
Which of the following is dominant trait in pea plant?
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted.
What phenotypes are possible if purple flowers are dominant to white flowers?
Here, purple flower is dominant and white flower is recessive in pea plants. Therefore, the presence of atleast one P allele will give purple colour (dominant phenotype) to the flower. Thus, the PP is a homozygous dominant genotype. Hence, the phenotype of PP is purple colour.
What is the dominant shape of a pea pod?
The dominant shape of a pea pod is smooth. You know because the smooth trait shows up in the F1. That’s why its allele is a capital letter. The symbol for the recessive allele for pod color is c (lower-case).
Which is recessive character in garden pea?
Detailed Solution. The correct is option 3, i.e., wrinkled seed. The wrinkled seed character is recessive in garden pea plants.
Which pod color is recessive?
Is yellow pod recessive or dominant? For pod color, there are two traits – green and yellow. Green pod color is dominant and yellow is recessive.
What are the contrasting characters of pea plant?
Mendel selected seven pairs of contrasting characters of pea plants for his experiments which are as follows:
- Pea shape: Round or Wrinkled.
- Pea color: Green or Yellow.
- Pod shape: Constricted or Inflated.
- Pod color: Green or Yellow.
- Flower color: Purple or White.
- Plant size: Tall or Dwarf.
