| Term | Definition |
|---|---|
| chromatid | an identical strand of a double stranded chromosome |
| a centromere | is a point where which the identical chromatids are joined |
| homologous chromosomes | contain genes for the same traits |
| you get one homolougs chromosome from | each parent |
| In the g2 phase, the cell continous to grow | and build structures needed for mitosis |
| chromatin is composed of thin strands of | DNA and protein |
| during cell division, chromotin condenses into | chromosomes |
| When a genetic disorder is inherited in a pattern in which the disorder corresponds to the recessive phenotype | autosomal recessive phenotype |
| Females have two x chromosomes so they would pass on | the x lined sex trait to the offspring |
| X-linked recessive inheritance is more common, | in females because they can be carriers of disease (meaning theyre heterozygous) but have a normal phenotype. |
| examples of x linked recessive dominance is | color blindness, hemophila, or muscular dystrophy |
| Males who inherit x lined recessive dominance either | have the disease or are genotypically normal (because Y does not have an allele for the genes) |
