In table the A is for chromosome and B is for gene. In the table first two points are same for both gene and chromosome. Both occur in pair. It is the pairing and segregation of the pair of chromosomes that leads to segregation of the pair of factor.

The answer is A indicates genes and B indicates chromoses

worng

a for chromosome and B for gene because first two point are same but third point are slightly different this help for distinguished our answer which column put tha chromosome and which gene

 A is chromosome b gene

A is chr and B is gene

A chromosome b gene

A is for chromosome 

B is for both gene awa chromosome (think twice)

A is gene and B is chromosome because for A  last point is given as " independent pairs segregate independently of each other" 

so for a gene pair to segregate independently they should be first independently paired as  linked pair of genes cannot segragate independently so i think A is gene

also 

chromosomes not show linkage so they are always independently paired thus " one pair segregates independently of another pair " represents chromosomes 

Hello

A is chromosome and B is gene

A is gene B is chromosome

A is chromosome 

A is chromosome and B is gene as in third point it indicates chromosomes are always independent but genes may be linked not always independent
