Bio Study Sets 12-16

sapling learning assignments: meiosis & genetics

Question/TermAnswer/Definition
Are eukaryotes, bacteria, microscopic organisms, egg & sperm cell cell considered haploid or diploid? Haploid
How does meiosis generate genetic variability? When homologous pairs line up at the center during metaphase Chromatids cross over in prophase I
What does a test cross determine? A test cross determines the genotype of an individual
What happens during the heating stage of PCR? Two strands of DNA are seperated
Meiosis II Sister chromatids fail to seperate Results in one cell that is n+1, n-1, and two normal cells NO crossing over
Meiosis I Homologous chromosomes fail to seperate Results in four abnormal cells
complete dominance when one trait over powers another ex: purple plant + white plant = purple plant
incomplete dominance blending of two traits; both are equally powerful ex: mom w/ curly hair + dad w/ straight hair = son w/ wavy hair
codominance both traits are fully expressed; each trait is shown ex: mom w/ blood type A + dad w/ blood type B = daughter w/ AB blood
allele variation of a gene B or b
genotype genetic makeup of an organism/DNA sequence Rr
gene a protein coding region on a chromosome
homologous matched pairs of chromosomes in a diploid cell
meiosis special type of cell division the begins with a diploid cell and produces 4 haploid cells that are genetically different from each other
heterozygous alleles in a diploid cell that are different
mitosis results in 2 genetically identical cells

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.
