| Question | Answer |
|---|---|
| Heredity | the passing on of physical or mental characteristics genetically from one generation to another |
| Purebread | Same color |
| Trait | Characteristic |
| Meiosis | a type of cell division that results in four daughter cells, each having half the number of chromosomes of the parent cell |
| Haploid | having a single set of unpaired chromosomes |
| Diploid | containing two complete sets of chromosomes, one from each parent |
| Hybrid | an organism that has different alleles for a trait |
| Phenotype | physical features |
| Genotype | genetic makeup |
| Offspring | an organisms child |
| Alleles | different forms of a gene |
| Homozygous | same traits |
| Heterozygous | different traits |
| Mutation | a change in a gene or chromosome |
| Sex-Linked Genes | genes on the X and Y chromosome |
| Carrier | a person that has one recessive allele for a recessive trait and one dominant allele |
| Sex Chromosomes | are one of the 23 pairs of chromosomes in each body cell |
| Pedigree | Family tree/chart that tracks which members of a family have a particular trait |
| Selective Breedings | selecting organisms with a desired trait to be the parent of the offspring |
| Inbreeding | crossing two individuals that have the similar characteristcs |
| Hybridization | breeders cross two genetically different individuals |
| Genetic Engineering | genes from one organism are transferred into the DNA of another organism |
| Gene Therapy | inserting copies of gene directly into a person's cells |
| Hybrid | an organism with 2 different alleles as a trait |
| Gene | set of information that controls a trait |
| Dominant | an allele that always shows up when the allele is present |
| Recessive | an allele that is masked when the dominant allele is present |
| Insertion | addition of one or more |
| Deletion | mutation where part of a chromosome or DNA is missing |
| Substitution | a mutation where one base pair is replaced with a different base pair |
| Genetic Disorder | abnormal condition that a person inherits through genes/chromosomes |
| Clone | an identical (genetically) that is a replica to the organism it came from |
