Solution

Phenotypes of the offspring:

  1. Tall Yellow: 3
  2. Tall Green: 3
  3. Dwarf Green: 1
  4. Dwarf Yellow: 1
  1. Proportion of tall and green is 3/8.
  2. Proportion of dwarf and green is 1/8.

Pooja has green eyes while her parents and brother have black eyes. Pooja’s husband Ravi has black eyes while his mother has green eyes and father has black eyes.

a. On the basis of the above given information, is the green eye colour a dominant or recessive trait? Justify your answer

b. What is the possible genetic makeup of Pooja’s brother’s eye colour?

c. What is the probability that the offspring of Pooja and Ravi will have green eyes? Also, show the inheritance of eye colour in the offspring with the help of a suitable cross.

OR

c. 50% of the offspring of Pooja’s brother are green eyed. With help of cross show how this is possible.


Assertion (A): In humans, if gene (B) is responsible for black eyes and gene (b) responsible for brown eyes, then the colour of eyes of the progeny having gene combination Bb, bb or BB will be black only.

Reason (R): The black colour of the eyes is a dominant trait.
