| chromosome | structure in nucleus that is made up of DNA and protein |
| asexual | production of offspring from 1 parent |
| sexual | production of offspring from 2 parents |
| meiosis | cell division that produces haploid cells |
| haploid | contains only 1 of each chromosome |
| chromatid | one half of a chromosome |
| centromere | holds together 2 chromatids |
| centriole | grows spindles that pull chromosomes to poles |
| diploid | contains 2 of each chromosomes |
| male gamete | sperm |
| female gamete | egg |
| budding, fission, spores | types of asexual reproduction |
| fertilization | joining of gametes |
| speed, less energy, more | advantages of asexual |
| diversity/differences | advantage of sexual |
| zygote | cell formed in fertilization |
| heredity | passing on of traits |
| allele | choices or version of a gene |
| genotype | alleles of an offspring |
| phenotype | appearance of an offspring |
| Punnett square | tool for predicting possible outcomes |
| probability | math of outcome chance |
| pedigree | tool for examining family |
| dominant | allele that covers another |
| recessive | allele that gets covered up |
| homozygous | when 2 alleles are the same |
| heterozygous | when 2 alleles are different |
| Mendel | father of genetics |
| square | boys in pedigree |
| XY | guy alleles |
