Refers to a pattern of inheritance where an allele is located on an autosome.

Organic molecules that are the building blocks of protein.

What is a Chromosome?
A.
A sequence that comprises three DNA nucleotides that together code for a protein.

C.
The transfer of DNA between non-homologous chromosomes.
