Homozygous - Genes of an individual who have two copies of the same allele (HH or hh) for a particular gene, Heterozygous - Genes of an individual who has two different alleles (Hh) for a particular gene, Dominant - When the effects of an allele can be detected regardless of the other allele, Recessive - When the effects of an allele masked in the heterozygous condition, Genotype - The genetic composition of an individual, Phenotype - Observable traits of an individual, Law of Segregation - During gamete formation, two alleles for each gene separate as the homologous chromosomes move toward opposite ends of the cell during meiosis, Law of Dominance - If a dominant and recessive gene are present in a pair of alleles, the dominant gene will be expressed, Law of Independent Assortment - Each chromosome is inherited independent of the other chromosome following the law of independent Assortment, Gamete - Sex Cells, Autosome - A chromosome that is not a sex chromosome, Pleiotropy - The expression of multiple traits by a single gene (Marfan Syndrome) , Epistasis - One gene is masked by the expression of another (Pigmentation), Homologous - A pair of chromosomes are called, Polygenetic Inheritance - Variation in trait such height, Diploid - Body Cells...46 (2n) paired chromosomes, Haploid - Sex Cells... 23 (n) unpaired chromosomes ,
