• 4-20-2017 Dude, if you are going to speak the language you have to learn the words. When you don't know what the words mean, they are just holes in the page. When you don't know what the words mean, you don't know what you are saying. Go to and type "define homozygous", and do it again for every word you don't understand. Homo- is Greek for "same" and a zygote is the cell formed when a sperm joins with an egg. Logo or log is Greek for word or study and ana- is Greek for "beside" so "analogous" means "similar idea" while "homologous" means "same word. Everything in your list uses the same word for different things. Comparing a wing of a building to a wing of a bird is analogy.
