Mendel chose Pisum sativum (pea plant) for his experiments. He selected seven traits of pea plant. It excludes plant colour. He chose characters like flower colour, flower position, stem length, seed shape, seed colour, pod shape and pod colour.
Which of the following are characteristics of a pea plant?
Gregor Mendel cross-bred peas which had 7 pairs of pure-bred traits, which are as follows: Colour (green or yellow) Shape (round or wrinkled) Colour of pod (green or yellow)
What are 4 pea plant characteristics that he experimented with?
Mendel studied the inheritance of seven different features in peas, including height, flower color, seed color, and seed shape.
Which of the following relationship was not studied by Mendel?
Which of the following relationship was not studies by Mendel? Explanation: Mendel did not study pollen shape and flower colour inheritance together, as if he would have used these traits in dihybrid cross they would show linkage and tamper his results.
Which character of pea plant was not used by Mendel?
He selected seven traits of pea plant. It excludes plant colour. He chose characters like flower colour, flower position, stem length, seed shape, seed colour, pod shape and pod colour.
What were the 7 characteristics of pea plants being studied by Mendel?
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 did Mendel choose pea plant for his experiment Class 10?
Complete Answer:
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.
Why was the pea plant used in Mendel’s experiments?
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: Presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.
Why did Mendel choose pea plant as an experimental material?
Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
Which of the following does not show Mendel’s Law of inheritance Mcq?
Which of the following is NOT Mendel’s law of inheritance? Explanation: Law of hetrozygous is not the law of inheritance proposed by Mendel. Mendel had given three laws of inheritance which included law of dominance, law of segregation of gametes, and the law of independent assortment. 8.
What is true of Law of Independent Assortment Mcq?
Mendel’s Law of Independent Assortment states that “When alleles of more than one trait are followed together in the cross, the alleles of these traits assort independently to each other during gamete formation”.
Which of the following seed characters were studied by Mendel in his experiment?
There were 7 characters of the pea plant which were selected by Mendel for the experiments. 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.
What are the 3 laws of Mendel?
The law of inheritance was proposed by Gregor Mendel after conducting experiments on pea plants for seven years. Mendel’s laws of inheritance include law of dominance, law of segregation and law of independent assortment.
How many characters of pea plants were studied by Mendel?
7 pairs
7 pairs of contrasting characters in pea plants were studied by Mendel in his experiments. From 1856 to 1863, Mendel conducted pea plant hybridisation studies.
How did Mendel control pollination in pea plants?
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.
Which of the following is involved in the success of Gregor Mendel’s experiment?
The main reason for the success of Mendel was that he took one character at one time in his experiments of hybridization. So it was easy. Other scientists also performed cross-hybridization for many characters, this made the experiments complex and they could not accurately explain the results.
Which of the following statements is true regarding the law of segregation?
Answer: According to the law of segregation the only true statements are: A gamete receives only one gene copy. The gene copy recieved by gamete is selected randomly.
Which of the following statement is true regarding the law of segregation Mcq?
Thus, each gamete receives one allele for a trait and two types of gametes are formed; 50% gametes carry factor for dominance (T) and 50% carry the recessive factor (t). Thus, the correct answer is option C.
What is the exception of Mendel law of Independent Assortment?
Linkage is an exception to Mendel’s law of independent assortment. The law states that inherited genes are independent of each other. Linkage is an exception to this law as two genes are situated on the same chromosome, however, this is usually diminished when there is a crossing over of chromosomes.
What is meant by Monohybrid Cross and Dihybrid cross Mcq?
Monohybrid cross is a cross between two individuals that differ in only one observed trait. Dihybrid cross is a cross between two individuals that differ in two observed traits.
