Question

The female swamp wallaby, an Australian marsupial, has a diploid chromosome number of 10. How many different chromosomal arrangements are possible in the eggs of the swamp wallaby as a result of independent assortment?

Answer 1

Option C

Step-by-step explanation:

Options for the question are

A) 5

B) 10

C) 32

D) 64

Solution

It is given that the female swamp wallaby, an Australian marsupial has a diploid chromosome.

Thus,

`2n = 10\\`

On solving the above relation, we get -

`n = 5`

Now, we know that number of chromosome arrangement if the eggs are undergoing independent assortment is equal to

`2^n`

Substituting the values of "n" is above relation, we get -

`2^5\\= 2*2*2*2*2\\= 32`

Total 32 different chromosomal arrangements are possible in the eggs of the swamp wallaby as a result of independent assortment

Hence, option C is correct
