Study the following statements. 1. In a monohybrid cross, we study two characters. 2. Garden pea (Pisum sativum) reproduces asexually in nature. 3. In incomplete dominance, one gene (dominant) is mixed with the other gene (recessive). 4. Mendel choose seven visible characters, each with two contrasting forms. Which of the statements given above is are false?

Assertion (A) Mendel worked on garden pea (Pisum sativum).
Reason (R) Garden pea belongs to family-Malvaceae.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true, but R is not the correct explanation of A

C

A is true, but R is false

D

A is false, but R is true

If x is the phenotypic ratio of monohybrid cross for trait A and y is the phenotypic ratio of monohybrid cross for trait B, what would be the phenotypic ratio of a dihybrid cross involving traits A and B?

A

xy

B

x + y

C

x2 + y2

D

(xy)2

Read the passage carefully and choose the best answer to each question out of the four alternatives.
Manja, or the glass-coated string used for flying kites, not only poses threat to humans, animals and birds but also to trees. A study by the country's oldest botanical garden has revealed that it poses a great threat to trees. But how can a snapped string struck in a tree kill the tree? Apparently, it does so by allying with the creepers in the garden.
A research paper by three scientists of the Acharya Jagdish Chandra Bose Indian Botanic Garden, located in West Bengal's Howrah district, illustrates in detail how the manja, in collusion with climbers, does the damage. "The abandoned, torn kite strings act as an excellent primary supporting platform for the tender climbers, giving easy passage to reach the top of the trees. Lateral branches from the top of the climber and other accessory branches from the ground reaches the top taking support of the first climber, completely covers the treetop, thus inhibiting the penetration of sunlight," says the research paper.

How many pairs of contrasting characters in pea were selected by Mendel?

A

7

B

3

C

4

D

2

Directions: Seven different boxes A, B, C, D, E, F and G of different colours viz., Orange, Pink, Purple, Yellow, Blue, Red and Green are arranged one above the other. The box at the bottom of arrangement is numbered 1, the above box is numbered 2 and so on. B is immediately above E. More than two boxes are above the Orange box. The Yellow box is immediately below A. Only one box is between the Orange box and F. G is immediately above the Red box. Only one box is between B and the Pink box. Only two boxes are between the Pink and the Green box. Only two boxes are between the Yellow box and the Orange box. The Purple box is neither at the top nor at the bottom of the arrangement.B is above Pink box. C is immediately above F. Neither C nor G is a Yellow box. G is not a Orange box. Question: Which combination represents the position of C and its colour?

A

6-Green

B

6-Red

C

5-Purple

D

7-Blue

Incomplete dominance violated Mendel’s law of dominance.

A

True

B

False

D

Answer depends on the time of day when sampling is done
