| Question | Answer |
|---|---|
| Gregor mendel | founder of genetics; studied garden peas because they only have 7 traits |
| heredity | passing on of traits from parents to offspring |
| trait | genetically determined feature |
| pollonination | pollen moved from male anthers to female stigma, fertilized egg is a seed |
| cross pollination | cross between flowers of 2 plants |
| self pollination | pollen transfered in the same flower or flower of the same plant |
| true breeding | group of living things that produce offspring of the same trait as parents |
| monohybrid | parents that differ in 1 trait |
| dihybrids | parents differ in 2 traits |
| polyhybrids | parents differ in 3 traits |
| alleles | the 2 factors for each trait |
| law of dominance | one allele in a hybrid prevents expression of the other allele |
| dominant | prevents expression of another allele (capital letter) |
| recessive | not expressed unless there are 2 of them (lowercase letter) |
| law of segregation | alleles are separated into separate gametes during meiosis |
| law of independent assortment | alleles separate independently of one another during formation of gametes (dominant don't always show up together, and recessive don't always show up together) |
| pheonotype | way an organism looks |
| genotype | genetic makeup of organism |
| homozygous | same alleles |
| heterozygous | different alleles |
| rule of independent events | previous events do not affect the later occurrences |
| product rule | probability of independent events occurring together is equal to the product of these events seperately |
| punnett square | tool/chart used to show possible combinations of genes |
| how is the law of segregation (gamete formation) showed in punnett squares? | by putting the letter about the square |
| how is fertilization showed in punnett squares? | by joining letters in the boxes |
| testcross | used to determine the genotype of something showing the dominant trait |
| how do you do a testcross? | cross the organism showing the dominant trait(homozygous+heterozygous) with one showing the homozygous recessive trait |
| incomplete dominance | when the hybrid (heterozygous) gives a phenotype intermediate/in between the contrasting traits |
| codominance | when both alleles are expressed equally because both are dominant |
| dihybrid cross | 2 characteristics are tracked |
| how do you do a dihybrid cross? | write genotypes of parents, foil, write alleles on top/bottom, fill out squares |
