Question

What are the haploid numbers for the fern and onion plants?

Answer 1

The diploid number of the fern and onion plants are

fern: 1010
onion plant: 16

The formula of the diploid is 2N where N represents the haploid number.

Diploid = 2N ;

fern:
1010 = 2N
1010/2 = N
505 = N ;

onion plant:
16 = 2N
16/2 = N
8 = N

The haploid number for the fern is 505 and the haploid number for the onion plant is 8.
