| show | (also, map unit) relative distance that corresponds to a 0.01 recombination frequency = 1 cM
🗑
|
||||
| show | average number of crossovers between two alleles; observed as the number of nonparental types in a progeny's population
🗑
|
||||
| show | theory proposing that chromosomes are the genes' vehicles and that their behavior during meiosis is the physical basis of the inheritance patterns that Mendel observed
🗑
|
||||
| show | process by which one chromosome segment dissociates and reattaches to a different, nonhomologous chromosome

🗑
|
||||
| Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human X chromosome The pts have muscles that weaken over time bc they have absent or decreased dystrophin How likely is it for a woman to have this condition? | show 🗑
|
||||
| show | recessive, sex-linked
🗑
|
||||
| show | 1/2
🗑
|
||||
| show | Mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis.
🗑
|
||||
| show | The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.
🗑

|
||||
| Which of the following statements correctly describes the reason that closely linked genes are typically inherited together? | show 🗑
|
||||
| If cell X enters meiosis, and nondisjunction of one chromosome occurs in one of its daughter cells during meiosis II, how will this affect the gametes at the completion of meiosis? | show 🗑
|
||||

|
||||
| show | tortoiseshell females; black males
🗑
|
||||
