Stack #4554377

QuestionAnswer
father of genetics who studied pea plants Gregor Mendel
"type" that is based on genetic information (alleles pairs) genotype
"type" that is based on physical trait (visible appearance) phenotype
different form of the same gene Example: A & a allele
segment of DNA that codes for a specific trait gene
genotypes made of the SAME alleles Example: GG homozygous
genotypes made of DIFFRENT alleles Example: Gg heterozygous
allele that is ALWAYS expressed ; only needs 1 upper cased letter dominant
allele that is only expressed in the homozygous state ; need 2 lower cased letters recessive
Mendel's research using only "either or" traits (2 options) complete dominance
Diagram used to predict the genotype of the offspring Punnett square
Punnett square used to figure out the genotype of 1 of the parents when the offspring's info is known (other parent is homozygous recessive) test cross
1 out of 4 to percent 25%
2 out of 4 to percent 50%
4 out of 4 to percent 100%
3 out of 4 to percent 75%
0 out of 4 percent 0%
their information will be placed inside a Punnett square offspring's genotypes
their information is placed outside of a Punnett square parents' genotypes
single trait caused by many genes polygenetic trait
when 2 genes are likely to be inherited together because they are close on the chromosome genetic linkage
Punnett square that looks at 2 traits using 16 boxes dihybrid cross
Punnett square that looks at 1 trait using 4 boxes monohybrid cross
2 factors that make up most human phenotypes genotype and environment
states that the inheritance of alleles for 1 trait has zero effect on the inheritance of alleles for another trait law of independent assortment
blood alleles that illustrate co-dominance blood alleles A and B
blood alleles O

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.
