Because the allele that produces wrinkled peas is recessive, the offspring of this cross will all have wrinkled peas.
What is a recessive trait in peas?
Mendel’s experiments showed that green is the recessive seed color in pea plants.
What is an example of a recessive trait in pea plants?
The recessive trait does, however, reappear in the progeny of the hybrid offspring. An example of a dominant trait is the violet-flower trait. For this same characteristic (flower color), white-colored flowers are a recessive trait.
Which trait of garden pea is recessive?
Wrinkled seed is a recessive trait.
What are pea plant traits?
The characteristics of a pea plant are:
- Colour of seed (green or yellow)
- Shape of seed (round or wrinkled)
- Colour of pod (green or yellow)
- Shape of pod (constricted or inflated)
- Size of the plant (tall or dwarf)
- Position of flowers (axial or terminal)
- Colour of flower (purple or white)
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 |
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 are 2 examples of recessive traits?
Examples of Recessive Traits
Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits. Having round (as opposed to almond-shaped) eyes is recessive, along with inability to roll one’s tongue.
Which of the following is dominant trait in pea plant?
So, the correct answer is ‘green pod‘.
Which genes are recessive?
A recessive gene is a gene whose effects are masked in the presence of a dominant gene. Every organism that has DNA packed into chromosomes has two alleles, or forms of a gene, for each gene: one inherited from their mother, and one inherited from their father.
Which of the following trait is not recessive in garden pea plant?
The axial flower position was recessive to the terminal position; green seed colour was recessive to yellow colour; yellow pod colour was recessive to green and wrinkled seed shape was recessive to round shape. The correct answer is B.
How many of the following is a recessive garden pea?
Solution : Green seed colour was a recessive characters. This Mendel’s experiment.
Why is the pea wrinkled seed allele a recessive allele?
Answer and Explanation: The allele for wrinkled seed shape in garden peas is considered recessive because the trait associated with the allele is not expressed in heterozygotes. Heterozygotes are individuals that have two different alleles for a particular gene locus.
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Is recessive a hidden trait?
Humans have two versions of all autosomal genes, called alleles, one from each parent. The recessive trait is hidden in the heterozygous individual (Dd) if the other allele is inherited in a dominant fashion, and so this person is a called a “carrier” of the recessive allele, but does not manifest the disease or trait.
What is pea plant called?
pea, (Pisum sativum), also called garden pea, herbaceous annual plant in the family Fabaceae, grown virtually worldwide for its edible seeds.
How many traits did each pea plant characteristics have?
During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms (Figure 3). The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or winkled), pea color (green or yellow), and so on.
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.
Are yellow or green peas dominant?
Yellow peas (I) are dominant to green peas (i). The I gene is on chromosome 1. In all pea plants, immature peas are green.
Is round or wrinkled dominant?
In Mendel’s experiments with garden pea, round seed shape (RR) was dominant over wrinkled seeds (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy).
Is 5 fingers a recessive trait?
But sometimes something goes wrong and an animal ends up with extra or missing digits. And surprisingly, having five fingers in these cases is usually a recessive trait. When people or animals are born with extra fingers this typically dominant trait is called polydactyly.
