genetics - Learning how traits are passed down from parents to offspring., gene - Made up of DNA. Carry the information about the specific traits that are passed down, DNA - The actual code or information about the traits, chromosome - Made up of DNA, they tell the cell what to do, Gregor Mendel - Father of genetics. He studied pea plants and learned traits were passed down., allele - Specific sequence of DNA that relates to traits like hair or eye color., nucleotide - Make up DNA. There are 4 that combine in many different ways, nucleus - The brain of the cell. Contains the chromosomes that tell the cell what to do., double helix - The shape of DNA. Looks like a twisted ladder, Watson & Crick - Discovered the double helix shape which helped scientists learn even more about DNA, heredity - When certain traits are passed down from one generation to the next., dominant - When present, this trait will always be seen, like brown eyes, recessive - This trait will only be seen if you have 2 matching genes of the same trait, like blue eyes, genome - The complete set of instructions of DNA in the cell, variation - The traits you inherit mix and combine in different ways so we all look different from one another, mutation - Accidents that occur when genes are passed down from parent to child., forensic - The use of DNA to help solve crimes., genetic modification - When scientists change genes in the lab to make something stronger or better., gene therapy - When doctors can fix a broken gene. They are still working on this., clone - Two organisms that have exactly the same set of genes,
