In meiosis, the original cells

In meiosis,the original cells are diploid i. e. double number of chromosomes.

Explanation: Meiosis is a type of cell division in which a single parent cell is divided into four daughter cells having half number of chromosome. The original or parent cell is divided into the two daughter cells in meiosis 1. Both parent and daughter cells are diploid. But in the end of meiosis 2,these two daughter cells are again divided into four daughter cells. These daughter cells are haploid i. e. half number of chromosome.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

b is dominant over the allele for the white fur.
