chap 14 study guide

biology - chapter 14: Mendel and the Gene Idea (exam 3)

QuestionAnswer
allele Alternative variations in genes (Alleles account for variations in inherited characters)
dominant allele dominant determines the organism's appearance (if an organism inherits 2 different alleles for a trait)
recessive allele has no effect on the organisms appearance
homozygous a pair of matching alleles
heterozygous a dominant allele paired with a recessive allele
genotype (gene) genetic makeup (example: TT, Tt, tt)
phenotype (physical) physical appearance (example: Tall plant[TT], Tall plant[Tt], Short plant[tt])
testcross used to figure out the genotype of an individual with the DOMINANT phenotype
true-breeding when plants self pollinate and produce ONLY the SAME variety as the parent plant
incomplete dominance heterozygote has intermediate phenotype
codominance (AB blood type is one example) more than one allele is fully expressed
ABO blood types 3 alleles for same gene control blood type (I^A , I^B, i)
pleiotropy a single gene can effect more than one trait
autosomes (X and Y) chromosomes OTHER than sex chromosomes
monohybrid cross CROSSED true-breeding varieties of pea plants that varied in only ONE trait (purple flowers + white flowers CROSS and produce purple flowers)
dihybrid cross CROSSED true-breeding plants that varied in TWO traits (example: [P generation= TTGG x ttgg] [P gametes= TG and tg] [F1 generation= TtGg])
Punnett square used to predict what type of offspring parents may have
P generation parental generation (top on flower diagram)
F1 generation first generation of offspring (middle section on flower diagram)
F2 generation second generation of offspring (bottom section on flower diagram)
gamete have only ONE allele for each trait
genotypic ratio example: 1PP:2Pp:1pp
phenotypic ratio example: 3 purple:1 white (corresponds with example for genotypic ratio)
epistasis interaction of genes that are not alleles

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.
