Question

1. If an organism's diploid number is 14, how many unique possible combinations of chromosomes can be inherited in the generated haploid reproductive cells? explain your answer.

128

512

7

14

28

Answer #1

Given the haploid number of chromosomes **(n)** ,
the number of possible combinations in of chromosomes that can be
inherited in the generated haploid reproductive cells or gametes
can be calculated by the equation
**2****n.** For example, in a diploid
cell with 4 chromosomes (n=2) so the number of chromosome
combination is 22 or 4.

Applying the formula in the question

here , 2n=14

n=7

2n=27=128

Answer is 128

How do mitosis and meiosis differ from each other?
The goal of mitosis is to produce cells that are genetically
identical to the original parent cell; the goal of meiosis is to
produce cells that contain twice the number of chromosomes as the
original parent cell.
The cells formed by mitosis are diploid; the cells formed...
