Question

Characters chosen by Mendel were located on how many chromosomes?
A. 4
B. 14
C. 7
D. 49

Answer 1

Hint: Augustine, the first person to lay the mathematical foundations of genetic science, in what became known as Mendelism, is Gregor Mendel, botanist, teacher, and prelate.

Complete Answer:
There were seven characters from the pea plant that Mendel picked for the experiments. Stem height, flower colour, flower place, pod shape, pod colour, seed shape, seed colour were the characters that were chosen by Mendel for his research. In a pea plant, all these characters belong to different chromosomes.

On 4 chromosomes, the characters which Mendel chose were located.
- Chromosome 1-Color of a seed coat and cotyledon
- Chromosome 4-Location of flower, pod shape and length of stem
- Chromosome 5-Color of pod
- Chromosome 7-The seed shape.

Fortunately, all the characters Mendel selected had their genes found on various chromosomes. In all cases, the rule of independent assortment will not function because the inheritance units will be transferred as a pair to the next generation, and not independently.

Mendel wanted to experiment with peas because they had four major attributes:
- Peas (all offspring will have the same characteristic generation after generation) have been shown to be true-breeding.
- A number of contrasting characteristics (purple vs. white flowers; round vs. wrinkled seeds) are demonstrated by peas.
- He was covered from foreign pollen by the form of the pea flower. Peas typically reproduce by self-pollination, in which eggs in the same flower are fertilised by pollen released by a flower.

The correct Answer is option (A) 4.

Note: The characteristics which Mendel studied are described below:
1. Ripe seed shape (R): smooth or wrinkled
2. Crop albumen (Y) colour (yellow or green)
3. Flower colour (P) -purple or white
4. Shape of inflated or constricted ripe pods (I)
5. Green or yellow colour of unripe pods (G)
6. Flowers position (A)-axial or terminal
7. Stem Length (T)-Tall or Dwarf
