2022 Genetics Intro

QuestionAnswer
alternative form of a gene allele
X-shaped structure containing many genes chromosome
"same" alleles (HH or hh) homozygous
"different" alleles (Hh) heterozygous
genetic makeup genotype
physical appearance phenotype
study of inheritance genetics
diagram used to predict genotype & phenotype of offspring Punnett Square
trait only requiring 1 upper cased letter to be expressed dominant trait
trait required 2 lower cased letters to be expressed recessive trait
inheritance pattern with only 2 possible phenotypes; one trait is dominant over the other (red x white = red heterozygote) complete dominance
two things that help form phenotype genotype + environment
process using a recessive parent to find the unknown genotype of the other parent Test Cross
segment of DNA on a chromosome that codes for a specific trait gene
inheritance pattern where the dominant trait is not completely dominant (red x white = pink heterozygote) incomplete dominance
inheritance pattern where both traits are dominant & equally expressed (red x white = red & white heterozygote) co-dominance
Universal Donor Type O
Universal Recipient Type AB
female genotype XX
male genotype XY
inheritance pattern where males are the MOST affected x-linked/ sex-linked
someone that has normal phenotype but can pass a recessive allele to their offspring carrier
father of genetics Mendel
examples of sex-linked traits (disorders) hemophilia, color blindness, baldness, muscular dystrophy

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.
