Mendel chose pea plants because they had easily observable characteristics and there were two contrasting observable traits of each character. There were seven pairs of such contrasting characters seen and used (manipulated) by Mendel for his experiments.
Why did Mendel choose the pea plants to compare the characteristics?
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 select garden pea plants?
(a) (i) Mendel selected garden pea plant for his experiment on heredity because it is self pollinating and self fertilizing plant so pure lines are easily available.
What happens when pea plants showing two different characteristics?
Answer. Answer: If the inheritance of more than one pair of characters is studied simultaneously the factors of genes for each pair of characters sort out independently.
What happens when pea plants showing two different characteristics rather than just one are bred with each other Class 10?
According to this law when two characters are taken into consideration for a cross (dihybrid cross), each one of these characters is independent to pass in the subsequent generation. It means that inheritance of a pair of factors or genes is independent of the other pairs of factors or genes.
What happened when Mendel crossed to treat of a character in a pea plant?
In one of the experiments with pea plants, Mendel observed that when a homozygous tall pea plant (TT) is crossed with a homozygous dwarf pea plant (tt), in the first generation, only tall plants appear.
Which of the following characteristics of pea plants was not used by Mendel in his experiments?
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.
Why was it important for Mendel to remove the anthers from pea plants in his experiments when crossing two different true breeding pea plants?
Why was it important for Mendel to remove the anthers from pea plants in his experiments when crossing two different true-breeding pea plants? You have an F2 generation derived from two true-breeding parents with different characteristics for the same trait (determined by a single allele).
Why in nature do we find more tall pea plant than dwarf pea plant?
Expert-verified answer
Gene for tall plant is T and dwarf plants is t. In nature, tall pea plant is found more because it is a dominant trait. Mendel came to know this when he performed cross between pure breeding tall ( TT) and pure breeding dwarf plant ( tt).
What Did Mendel’s cross-pollination of pea plants prove?
Mendel’s cross-pollination of pea plants proved that genes of two separate organisms are passed to their offspring.
How did Mendel use pea plants to discover how traits are inherited?
To do so, he first established pea lines with two different forms of a feature, such as tall vs. short height. He grew these lines for generations until they were pure-breeding (always produced offspring identical to the parent), then bred them to each other and observed how the traits were inherited.
What were two factors responsible for Mendel’s success?
What were two factors responsible for Mendel’s success? He studied only one trait at a time and analyzed the data he collected mathematically. You just studied 25 terms!
Which is a dominant trait that Mendel observed in pea plants?
Having smooth seeds is a dominant trait. Which descriptions apply to Mendel’s pea plant experiments?
Which is a character of a pea plant?
Shape (round or wrinkled) Colour of pod (green or yellow) Shape of pod (constricted or inflated) Size of the plant (tall or dwarf)
Which of the following Mendel has selected for his experiment?
garden pea plants
Mendel selected the garden pea plants for his experiments.
What are the seven characters that Mendel studied in 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)
What was unique about Mendel’s approach to explain his pea experiment results?
By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding. The garden pea also grows to maturity within one season, meaning that several generations could be evaluated over a relatively short time.
What happen when we cross the tall and dwarf varieties of garden pea?
A cross between pure breeding tall (TT) and dwarf (tt) plants produce all tall (Tt) plants in F1 progeny. These heterozygous tall plants produce 50% gametes with “T” allele and 50% with “t” allele. Random fusion of these gametes from two heterozygous tall plants gives tall and dwarf plants in 3:1 ratio.
What is dominant character?
Definition. (genetics) An inherited trait that results from the expression of the dominant allele over the recessive allele. Supplement. The inheritance of one or two copies of the dominant alleles results in the expression of a dominant trait.
Why were the dwarf plants not formed in the F1 generation?
Expert-verified answer
dont not appear the F1 generation are the dwarf plants. This is because the dwarf plants are homozygous recessive alleles. The recessive character does not appear in the presence of the dominant character .
What was the purpose of Mendel’s experiment?
Mendel did not set out to conduct the first well-controlled and brilliantly-designed experiments in genetics. His goal was to create hybrid pea plants and observe the outcome. His observations led to more experiments, which led to unusually prescient conclusions.
