_________________________ Father of Genetics
_________________________ traits that show up frequently in a population
_________________________ passing of traits from parent to offspring
_________________________ gene combination represented by letters
_________________________ 4 types: A, B, AB, and O
_________________________ two different alleles, ex. Aa
_________________________ two of the same alleles, ex. BB
_________________________ hides when a dominant form is present
_________________________ X-shaped structures, made of wound up DNA, located in the nucleus
_________________________ build all living things
_________________________ describes an organism’s physical appearance (what the trait looks like)
_________________________ a form of a gene; either dominant or recessive
_________________________ contains the information that tells the cell what to do (contains the DNA)
_________________________ a 2x2 grid that helps determine how alleles are inherited
_________________________ sections, or bands, of a chromosome, that code for a certain trait (ex: eye color)
_________________________ what chromosomes and genes are made of; a chemical that holds the recipe for life
_________________________ Mendel did this with 2 plants in order to produce offspring
_________________________ when genes are (?), they show up together (ex: blood type)
_________________________ Cells divide to make more cells. When we make more cells, we can grow bigger. We
have more cells now, as teenagers, than we did as babies. These cells are exact
copies of the first cell that made us.
_________________________ Cells have a lifespan and eventually die. We need to make more cells to replace the
dead cells. Cells can also become damaged and die (i.e. a burn, a cut, a broken
bone). Cells need to divide to fix the injury. These cells are just like the body cells
we make to grow – exact copies of our first cell.
_________________________ Males have special cells called sperm. Females have special cells called eggs. These
cells contain half of a person’s genes. When a sperm cell meets an egg cell, the
genes combine to make 1 cell with a full set of genes. This is the first cell to make a
human being.
