Out of the seven pairs of contrasting traits studied by Mendel in pea plant, round seed shape, yellow seed colour, violet flower colour, inflated pod shape, green pod colour, axial flower position and tall stem height are dominant traits.
What are the dominant traits in pea plants?
So, the correct answer is ‘green pod’.
How many dominant characteristics are present in pea plant from given list?
Axial flower, yellow pod, flower position, pod shape, terminal flower, wrinkled seed, tall plant, white flower, seed shape.
What are the seven traits of pea plants that Mendel worked with?
The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.
Which of the given traits are dominant traits?
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
What are dominant and recessive traits class 10?
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 these is not a dominant trait of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
What are the dominant and recessive characters of pea plant?
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.
Why Mendel choose pea plant for his experiment Class 10?
Mendel choose pea plants for his experiments because of the following reasons: (i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iii) The different physical characteristics were easy to recognize and study.
What are 4 examples of dominant traits?
Examples of Dominant Traits
- Dark hair is dominant over blonde or red hair.
- Curly hair is dominant over straight hair.
- Baldness is a dominant trait.
- Having a widow’s peak (a V-shaped hairline) is dominant over having a straight hairline.
- Freckles, cleft chin and dimples are all examples of a dominant trait.
What are dominant traits are defined as?
dominant trait. In genetics, a trait that will appear in the offspring if one of the parents contributes it. (Compare recessive trait.)
What are some dominant and recessive traits?
Gene expression determines our phenotype. Some of these genes (dominant) mask the effect of others (recessive).
Single Gene Traits.
| Traits | Dominant | Recessive |
|---|---|---|
| Hairline | Widow’s peak | Straight |
| Hair color | White hair streak | Normal hair color |
| Handedness | Right handedness | Left handedness |
| Hitchhiker’s thumbs | Absence | Presence |
What are the dominant traits class 10?
– Dominant trait is the first that appears or expressed visibly in the organism. For example- Baldness, Curly hair is dominant over straight hair etc. Dominant allele is expressed in capital letters like A versus a. Each parent provides one allele, the combinations are: AA, Aa, and aa.
What do you mean by dominant character class 10?
Dominant trait: The trait which can express its effect over contrasting trait is called a dominant trait. It is expressed even in the presence of one copy of an allele for a particular character in the gene, i.e., it is expressed in the heterozygous condition.
What are dominant and recessive traits class 12?
Hint: Recessive traits are the traits that are only expressed when the progeny contains two copies of the recessive allele. A recessive trait is always homozygous ‘aa’. Dominant traits are the traits that are always expressed in the progeny when the dominant allele is present in either one or two copies.
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.
What are the seven characteristics or traits of the pea plant?
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)
What are three laws of Mendel?
The three laws of inheritance proposed by Mendel include:
- Law of Dominance.
- Law of Segregation.
- Law of Independent Assortment.
Why Mendel is called father of genetics?
Mendel was the first to give scientific explanation regarding the mode of transmission of characters and formulate the basic laws of heredity. Hence he is rightly called the ‘father of genetics’.
What are 4 examples of recessive traits?
Examples of Recessive Traits
- Attached earlobes.
- Inability to roll tongue.
- Five fingers.
- Type O Blood.
- Hitch-hiker’s thumb.
- Blue eyes.
- Albinism: an albino lacks pigment or coloration in the skin.
- Sickle cell anemia: abnormal red blood cells make it difficult to transport oxygen throughout the body.
What is an example of a dominant?
The definition of dominant is a person who is in a position of power or who is exhibiting powerful or controlling tendencies. An example of dominant is a strong and powerful CEO.
