1 Level Genetics Review KEY Describe the 3 laws that Gregor Mendel established after working with pea plants. a. Law of Dominance: states that the effect of a recessive allele is not observed when a dominant allele is present. Dominant MASKS the recessive allele. b. Law of Segregation: states that two alleles for a trait MUST separate when a gamete is formed (GAMETES are sex cells created during MEIOSIS) Therefore a parent passes only ONE allele for each trait to offspring. c. Law of Independent Assortment: Alleles separate and do not have an effect on another allele. 2. Define the following terms: a. Dominant- Trait observed and will mask other traits (denoted with Capital letters: T, D, B, R) b. Recessive- trait that will disappear when a dominant allele is present, only shows up when BOTH alleles are recessive (denoted with lower case letters: e, b, r, n) c. Heterozygous-organism is heterozygous for a trait if two alleles are DIFFERENT: Hh, Rr) d. Homozygous- organism is homozygous for a trait if two alleles are SAME: HH, RR, BB, rr, pp, vv) Also called PURE e. Purebred- organisms genotype contains same two alleles (homozygous: HH, TT, bb, rr) f. Hybrid-organism that contains two DIFFERENT alleles-heterozygous, Hh, Rr, Tt) g. Gene-segments of DNA that are found on chromosomes h. Allele-different types of trait-hh, BB, rr) always need two per offspring trait) i. Phenotype- the way organism looks or behaves j. Genotype- the gene combinations an organism contains for a trait. k. P generation- the PARENT generation l. F 1 generation- the FIRST generation offspring m. F 2 generation- the second generation offspring 3. In some species of plants, crossing red flowers with white flowers produces pink flowers. What type of dominance is this called in genetics? Incomplete 4. In some species of chickens, there are two dominant alleles for feather color. What is the appearance of the offspring when a black dominant rooster is crossed with a white dominant hen? Checked What kind of dominance is displayed? Co- dominance

2 5. Some of our traits are determined by more than one pair of alleles, such as blood type and hair color. What are these types of traits called? Multiple Alleles Delete #6 7. If an organism s diploid number of chromosomes is 36 chromosomes, what is its haploid number of chromosomes? What does a Punnett square show us? Offspring of F1 generation 9.
