The passing of traits from the parents to offspring is known as? Heredity
A physical characteristic that and organism has? Trait
The study of heredity is known as? Genetics
The mathematical chance that something will happen? Probability
This trait will always show up in an organism when the allele is present. Dominant
The combination of genes (letter combination) is called what? Genetype
The part of the DNA that determines our traits? gene
If an organism has one dominant allele and one recessive allele (Dd), then they are said to be? Heterozygous
If an organism has two dominant traits (TT) or two recessive traits (tt),then they are considered? Homozygous
One single gene is called (T)? Allele
This trait will only show if there is no dominant trait present Recessive Trait
This is used to determine the possible variations of offspring? Punnett Square

What base connects to Adenine Thymine
What base connects to Guanine Cytosine
Let's say that Round seed shape is dominant R and wrinkled is recessive r. If a plant has wrinkled seeds, what could the possible genotypes be? rr
The round seed shape is dominant R and the wrinkled is recessive r. If the plant has round seeds, what could be the possible genotypes? RR, Rr
If both parents have RR, then what percentage of the offspring will have wrinkled seeds? 0%
Parent 1: Genotype: RR, Phenotype: ? round
Parent 2: Genotype rr, Phenotype: ? wrinkled

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.
