| Genes | DNA segments |
| Homozygous Chromosomes | chromosomes that make up a pair, 1 chromosome from each parent. |
| Gametes | sex cells that have half the number of chromosomes. |
| Haploid | A cell with the number of N chromosomes |
| Fertilization | the process by which 1 haploid gamete combines with another haploid. |
| Meiosis | a type of cell division that reduces the number of chromosomes. |
| Crossing Over | a process during which chromosomal segments are exchanged between a pair of homozygous chromosomes. |
| Genetics | science of heridity |
| Homozygous | An organism with 2 of the same alleles for a particular trait. |
| heterozygous | an organism with 2 of the same alleles for a trait. |
| genotype | organism's allele pairs. |
| phenotype | observable characteristics or outward expression of an allele. |
| law of segregation | 2 alleles for each trait separate during meiosis. |
| hybrids | heterozygous organisms. |
| law of independent assortment | it states that random distribution of alleles occurs during gamete formation. |
| genetic recombination | the new combination of genes produced by crossing over and independent assortment. |
| polyploidy | occurence of 1 or more extra sets of all chromosomes in an organism. |
| allele | and alternative form generation to generation |
| dominant | form of trait appereance in f1 generation. |
| recessive | form of trait masked in f1 generation |
| diploid | a cell that contains 2n number of chromosomes. |
