Complete answer: Green cotyledon colour was one of the recessive traits studied by Mendel in garden pea.
Which of the following characteristics is recessive in a pea plant?
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.
Is pea character a recessive character?
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted. Inflated pod traits are dominant. The shape of the seed has two traits – round and wrinkled.
Which of the following is recessive trait?
Axial flower position, green pod colour and inflated pods are dominant traits whereas green colour of seeds is a recessive trait.
What is recessive and dominant trait?
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. If one of the alleles is dominant, then the associated characteristic is less likely to manifest.
Which of the following is a dominant character of pea plant?
So, the correct answer is ‘green pod‘.
What are the 7 characters of Mendel?
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 are the dominant and recessive traits of the pea plant’s seed shape?
The terminal flower position was recessive to axial position; yellow seed colour was recessive to green colour; green pod colour was dominant to yellow and round seed shape was dominant to wrinkled shape.
Which of the following is a recessive character of Mendel?
Complete answer: Green cotyledon colour was one of the recessive traits studied by Mendel in garden pea.
What are examples of recessive genes?
Examples of Recessive Traits
For example, having a straight hairline is recessive, while having a widow’s peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.
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.
What do recessive genes mean?
One gene in each pair comes from the mother, and the other gene comes from the father. Recessive inheritance means both genes in a pair must be abnormal to cause disease. People with only one defective gene in the pair are called carriers. These people are most often not affected with the condition.
What are dominant and recessive genes Class 10?
The gene which decides the appearance of an organism even in the presence of an alternative gene is known as dominant gene. The gene which can decide the appearance of an organism only in the presence of another identical gene is called a recessive gene.
Is BB dominant or recessive?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.
What are the 7 characteristics of pea plants?
On the next screen, he reveals that there are seven different traits:
- 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)
- Position of flowers (axial or terminal)
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.
How do Mendel’s experiments show that traits Maybe dominant or recessive?
Mendel’s experiments show that the Traits may be dominant or recessive by performing a monohybrid cross. Monohybrid cross between two pure breeding varieties always obtained hybrid progeny exhibiting one parental trait while the opposite trait was never expressed in the F1 generation.
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.
Is hybrid dominant or recessive?
A hybrid is called heterozygous, as it has two different alleles. The offspring from a pure tall pea plant, cross-pollinated with a pure short pea plant, will result in a heterozygous plant for tallness. No organism has all dominant or all recessive genes.
| Dominant | Recessive |
|---|---|
| Widow’s peak hairline | Straight hairline |
Are green seeds dominant or recessive?
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.
Why Mendel choose pea plant for his experiment Class 10?
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.
