QuestionAnswer
Somatic Cells: cells that make up most of your body tissues and organs
Gametes sex cells
Homologous chromosomes 2 chromosomes, one from dad and one from mom, of the same length and appearance
Autosomes chromosomes that contain genes for characteristics not related to the sex of the organism
Sex chromosomes chromosomes that control the sex of the organism
Sexual reproduction : involves the fusion of 2 gametes
Feralization fusion of egg and sperm
Diploid: cell with 2 copies of each chromos
haploid cell with only one copy of chromos
meiosis form of nuclear division that divides diploid into haploid
Gametogenisis production of genes
Sperm male gamete
egg female gamete
polar body cells with a little more DNA that is eventually broken down
trait characteristic that are inherited
genetics study of biological inhearitance
purebread geneticly uniform
cross mating of 2 organisms
law of segregation organisms inheirtite one from mom and one from dad, organism donate a part of these genes to their offspring
gene piece of DNA that provides a set of instructions
allele any of the forms of genes that may occur in locus
Homozygous 2 of the same alleles at a specific locus
Heterozygous 2 different allels at a locus
genome all of the organism genetioc material
genotype genetic make up to a set of genes
dominate the allele that is expressed when two different alleles or two dominant alleles are present
recessive allele that is expressed only when two copies are present
punnett square a chart that shows all the possible genotypes that can result from a genetic cross
monohybrid cross Crosses that examine the inheritance of only one specific trait
test cross a cross between an organism with an unknown genotype and an organism with the recessive phenotype
dihybrid cross crosses that examine the inheritance of 2 differeant traits
Law of Independence Assortment states that allele paris separate independently of each other during gamete formation, or meiosis.
probability the likelihood that a particular event will happen
crossing over the exchange of chromosome segments between homologous chromosomes during the prophase I and meiosis I
genetic linkage genes located close together tend to be inherited together

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.
