  1. $1:1:1:1$

  2. $1:4:6:4:1$

  3. $1:2:1$

  4. $1:6:15:20:15:6:1$

Show answer
Correct Option: C
Explanation:
When two genes present on the same loci give an additive or cumulative effect like the spotted and Dotted seed of Lens sps the ratio is 1:2:1
So, the correct answer is '1:2:1'

Show answer
Correct Option: C
Explanation:

The colour based contrasting traits studied by Mender in pea plant were pod colour,  i.e., green (dominant) and yellow (recessive), flower colour, i.e., violet (dominant) and white (recessive) and seed colour, i.e., yellow (dominant) and green (recessive). 

Mendel's laws were first published in the year

  1. 1875

  2. 1890

  3. 1928

  4. 1866

Show answer
Correct Option: D
Explanation:

Mendelian inheritance is a type of biological inheritance that follows the laws originally proposed by Gregor Mendel in 1865 and 1866 and rediscovered in 1900.

So, the correct option is '1866'.

Correct Option: A
Explanation:

Mendel’s law of inheritance were rediscovered by Hugo de vries, Tschemark, Correns. Hugo de vries republished the Mendel’s work in ‘Flora’.

  1. De Vries

  2. Tschermak-seysenegg

  3. Carl Correns

  4. T. H. Morgan

Show answer
Correct Option: C
Explanation:

Carl Erich Correns was a German botanist and geneticist, who is notable primarily for his independent discovery of the principles of heredity, and for his rediscovery of Gregor Mendel's earlier paper on that subject, which he achieved simultaneously but independently of the botanists Erich Tschermak von Seysenegg. He also converted Mendel’s conclusions into principles of heredity.

So, the conclusion is ‘Carl correns’.
