Answer:

C. 1,024

The answer can be worked out using 2^pairs of chromosomes

Explanation:

Imagine there were <u>two</u> pairs of chromosomes:

  • A paired with B
  • C paired with D

A gamete could have the following combinations:

  • A + C
  • A + D
  • B + C
  • B + D

Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities

Now, Imagine there were <u>three</u> pairs of chromosomes:

  • A paired with B
  • C paired with D
  • E paired with F

A gamete could have the following combinations:

  • A + C  + E
  • A + D + E
  • A + D + F
  • A + C + F
  • B + D + F
  • B + C + F
  • B + C + E
  • B + D + E

Therefore, with three pairs of chromosomes, there are 4 (2³) possibilities

For 10 chromosomes - there are 2¹⁰ possibilities. 2¹⁰ = 1024
