Genetics

All the vocabulary for the Genetics Unit

Question/TermAnswer/Definition
Heredity The inheritance of traits from parents to offspring
Genotype An organism's GENES (letters) EE, Ee, ee
Phenotype An organism's PHYSICAL appearance (observable traits) Eye color, hair color, stem length
Gene A code in an organism's DNA that codes for a specific trait
Allele Alternative forms of the same gene ( ex: B=brown eyes, b=blue eyes)
Homozygous Two of the same allele (BB or bb)
Heterozygous Two different alleles (Bb)
Dominant Alleles/genes that overpower or mask the effect of a recessive allele
Recessive Alleles that are hidden when a dominant allele is present. The only way to observe the this is when both alleles are recessive (bb)
Gregor Mendel The "Father of Genetics." He experimented on pea plants.
Theory of Dominance Dominant genes mask recessive genes. The only way to see recessive genes is to have only recessive genes.
Theory of Segregation There are 2 copies of each gene. In meiosis, each gene in a pair separate so that each sex cell has half the DNA.
Incomplete Dominance Complex genetics where each each gene is not completely dominant over the other. When both alleles are present you get a BLEND. Red flowers crossed with White makes PINK
Codominance Complex genetics where each gene is equally dominant over the other. When both alleles are present you SEE BOTH traits. Black chicken crossed with White makes a black and white chicken.
Sex-Linked Traits These genes are located on the sex chromosomes, usually on the X chromosome. Color-blindness and baldness are sex-linked traits.
Pedigree A family-tree that shows how genetic traits are passed down from one generation to the next. Squares=males, Circles=females, shaded in=disorder/trait
Blood Types Co-dominance where A is codominant to B, and O is recessive
Mutation A mistake in the DNA genetic code.
Karyotype A map of someone's chromosomes
Carrier A person who appears normal, but carries a recessive allele that they could pass to their offspring. Aa= Shows dominant trait, carries recessive allele XbX= Non-bald female, carries the baldness gene

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
