PRE-LAB QUESTIONS 7. The gametophyte of a fern is -1. In a monohybrid cross (a) only one trait is being considered (b) the parents are always dominant (c) the parents are always heterozygous (d) no hybrid is produced (a) haploicd (b) photoautotrophic (c) a structure that produces eggs and/or sperm (d) all of the above The genetic makeup of an organism is its (a) phenotype (b) genotype (c) locus (d) gamete 2. 8. A chi-square test is used to (a) determine if experimental data adequately matches what was expected (b) analyze a Punnett square (c) determine parental genotypes 3. An allele whose expression is completely masked by the expression or effect of its allelic partner is (a) homologous (b) homozygous (c) dominant (d) recessive producing a given offspring genotype determine if a trait is dominant or recessive (d) Possible gamete genotypes produced by an individual of genotype PpDd are (a) Pp and Dd (b) all PpDd (c) PD and pd (d) PD, Pd, pD, and pd 9. 4. The physical appearance and physiology of an organism, resulting from interactions of its genetic makeup and its environment, is its (b) hybrid vigor 10. If you can roll your tongue. you have at least one copy of the dominant allele T (a) (b) (c) you must be male (c) dominance (d) genotype you have two copies of the recessive allele t When both dominant and recessive alleles are present within a single nucleus, the organism is for the trait. (a) diploid (b) haploid (c) homozygous 5. (d) you are haploid 6. A Punnett square is used to determine (a) probable gamete genotypes b) possible parental phenotypes (c) possible parental genotypes (d) possible genetic outcomes of a cross
