learning how traits are passed down from parents to offspring
genetics
Made up of DNA. Carry the information about the specific traits that are passed down.
gene
made up of DNA, they tell the cell what to do
chromosome
The actual code or information about the traits
DNA
Father of genetics. He studied pea plants and learned traits were passed down.
Gregor Mendel
specific sequence of DNA that relates to traits like hair or eye color
allele
Make up DNA. There are 4 that combine in many different ways
nucleotide
The brain of the cell. Contains the chromosomes that tell the cell what to do
nucleus
the shape of DNA. Looks like a twisted ladder
double helix
Discovered the double helix shape which helped scientists learn even more about DNA
Watson & Crick
when present, this trait will always be seen, like brown eyes
dominant
when certain traits are passed down from one generation to the next
heredity
this trait will only be seen if you have 2 matching genes of the same trait, like blue eyes
recessive
the complete set of instructions of DNA in the cell
genome
accidents that occur when genes are passed down from parent to child
mutation
the traits you inherit mix and combine in different ways so we all look different from one another
variation
