Cyanobacteria play an important role in the biosphere by converting atmospheric nitrogen into mineral nitrogen directly assimilated by other organisms. This capacity is of fundamental importance in coral reefs where nutrients are scarce.

Moreover, Cyanobacteria are the micro-organisms of choice for humans in various branches of biotechnology because of the many families of molecules that they produce and which have an interest in valorization.

A particular plant has 10 pairs of chromosomes in each cell. For each of the plant's gametes, how many genetic combinations are
Law Incorporation [45]

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
