front 1 Law of Segregation | back 1 Alleles separate such that each gamete has only one allele after Meiosis |
front 2 Phenotype | back 2 Physical display of genes |
front 3 Law of Independent Assortment | back 3 Inheritance of a gene is not dependent on another if the genes are on separate chromosomes. |
front 4 Complete or Simple Dominance | back 4 When a recessive allele is masked by a dominate in the heterozygote |
front 5 Incomplete Dominace | back 5 When heterozygotes have an intermediate phenotype between the two homozygotes |
front 6 Codominance | back 6 When both alleles are equally expressed in the heterozygote |
front 7 Epistasis | back 7 When one gene change the phenotype of another gene from a different chromosome |
front 8 Polygenic Inheritance | back 8 When two or more genes work together to affect a trait |
front 9 Recessive Genetic Disorders | back 9 Cystic Fibrosis, Tay Sachs Disease, Sickle Cell anemia |
front 10 Dominant Genetic Disorders | back 10 Huntington's Disease, Achondroplasia |
front 11 Sex-linked Genes | back 11 Genes carried on the "X" Chromosome |
front 12 Human sex linked traits | back 12 Hemophilia, Colorblindness, Duschenna Muscular Dystrophy |
front 13 Linked Genes | back 13 Genes carried on the same chromosome which are inherited together |
front 14 Nondisjunction | back 14 When chromosomes don't separate during Anaphase I and Anaphase II |
front 15 Barr Body | back 15 Structure that forms after one "X" chromosome is inactivated in a somatic cell |
front 16 Gametes | back 16 Sex cells of an organism |
front 17 Somatic Cells | back 17 Every cell other than the Gametes. |
front 18 Locus | back 18 A gene's specific location along the length of a chromosome |
front 19 Diploid Cell | back 19 Has two sets of chromosomal pairs (2n) |
front 20 Haploid Cell | back 20 Has one set of chromosomes (n) |
front 21 Zygote | back 21 Diploid cell that is an egg that is fertilized by sperm |
front 22 Meiosis I | back 22 First step in which sexually reproducing organisms divide making half the number of chromosome sets as the original cell |
front 23 Prophase I (Meiosis I) | back 23 Crossing over occurs, centrosome movement, spindle formation, nuclear envelope breakdown, Microtubules attach to the kinetochores |
front 24 Metaphase I (Meiosis I) | back 24 Homologous pairs are arranged in the middle of the cell, Each pair has a kinetochore microtubule attached to it |
front 25 Anaphase I (Meiosis I) | back 25 Breakdown of proteins between sister chromatids allowing the homologs to separate, homologs move towards opposite poles |
front 26 Telophase I and Cytokinesis (Meiosis I) | back 26 Each half of the cell has a complete haploid set of chromosomes, cytokinesis |
front 27 Meiosis II | back 27 Second step in which sexually reproducing organisms divide making half the number of chromosome sets from Meiosis I |
front 28 Prophase II (Meiosis II) | back 28 Chromosomes once again move to the Metaphase plate |
front 29 Metaphase II (Meiosis II) | back 29 Chromosomes are lined up at the Metaphase plate, microtubules extend from opposite poles |
front 30 Anaphase II (Meiosis II) | back 30 no data |
