What is the reason that linked genes are inherited together? a. they are located close together on the same chromosom b. the number of genes in a cell is greater than the number of chromosomes. c. chromosomes are unbreakable. d. alleles are paired together during meiosis. e. genes align that way during metaphase i of meiosis.

A little basic info:

Chromosomes are molecules of DNA that carry groups of genetic information. Some genes group up in the same chromosome, and this it what we'll see below.

Why are linked genes inherited together? What are they?

This question is more simple than it looks, since there's really little to explain. Linked genes, are genes inherited through the same chromosome:

→ When 2 genes tend to group-up on the same chromosome, they tend to be inherited together, but still, this doesn't happen always and the probablity of this happening is just slightly above 50%.

Remember:

Only genes that sit close together on a chromosome are likely to be inherited together, because if they're to far apart in the chromosome, the process of (homologous) recombination might separate them.

→ To make things simple, homologous recombination is when similar DNA moleculas are moved and recombined in a different way.
