INHERITANCE is the ability to pass on traits from one generation to another.
The first experiments on inheritance was from farmers. They made PUREBRED and HYBRID organisms to help them control the breeding of useful traits. Every population has variation and by selecting certain traits to breed, one can get a purebred characteristic. For example. Suppose there is a population of bunnies: white, brown, black, grey. If you wanted to get only grey baby bunnies, you can SELECTIVELY BREED the grey ones.
The first experiments to look at the LAWS OF INHERITANCE was conducted by GREGOR MENDEL, a monk. He called purebreds HOMOZYGOUS. He called hybrids HETEROZYGOUS.
A Gene is a section of DNA which codes for a protein. Note how it looks in Chromatin form and also Chromatid form.
A chromosome usually refers to a duplicated chromatid. It is a double copy of the DNA for the purpose of asexual or sexual reproduction. Chromosomes become visible only during reproduction.
Chromatids are HOMOLOGOUS, that is, they come in pairs. In Eukaryotes, a PAIR OF GENES located on a PAIR OF CHROMATIDS codes for one trait.
