QuestionAnswer
The farther apart two genes are located on a chromosome..? the less likely they are to be inherited together
Linked genes: are on the same chromosome
Why is the chromosome number reduced by meiosis? because between meiosis 1 and meiosis 2, replication does not occur
How are gametes produced? by meiosis
What do most dihybrid crosses show? they show which genes sort independently
Which of Mendel's principles explains why offspring inherit two recessive genes? the principles of dominance and segregation
How do we represent the number of chromosomes in a gamete? the letter N
Gametes have: one allele for each gene
Organisms that have two identical alleles for a particular trait are said to be: homozygous
In Mendel's experiment, the probability that an F2 plant would be tall was: 3:1; 75%
If alleles did not segregate during gamete formation: all of Mendel's F2 plants would have been tall
When Mendel allowed the tall F1 pea plants to self-pollinate: some of the offspring were short
If a pea plant has a recessive allele for green peas it will produce: green peas if it does not also have the dominant allele for yellow peas
The principle of dominance states that: some alleles are dominant and others are recessive
In Mendel's experiments, the F1 plants inherited: an allele for tallness from the tall parent and an allele for shortness from the short parent
What are Mendel's factors called today? genes
Mendel removed the male parts from the flowers of some plants in order to: to make controlled crosses between plants

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.
