Biology 11 Chap 5.3
Genetic Processes: 5.3 Patterns of Inheritance
| Question | Answer |
|---|---|
| alleles | one of two or more alternative forms of a gene that are found on the same place of a chromosome |
| autosomal dominant or recessive | the gene of interest is found on one of the autosomes (1 – 22 in humans) and individuals that are affected acquire the trait by possessing either a dominant copy of the allele (autosomal dominant) or a recessive copy of the allele (autosomal recessive) |
| autosomes | one of the non sex chromosomes. In humans it is one of chromosomes 1 - 22 |
| carrier | a type of autosomal recessive inheritance pattern in which an affected individual received the allele from parents that were both heterozygous. |
| gene | a unit of heredity that is transferred from a parent to an offspring and determines some characteristic |
| gene therapy | The transplantation of normal genes into cells in place of missing or defective ones in order to correct genetic disorders. |
| genetic screening | testing a population (or an individual) to identify individuals at risk for a genetic disease or for transmitting it |
| heredity | the passing of genetic characters from parent to offspring |
| hybrid | a genotype in which there is a mixture of dominant and recessive alleles |
| pedigree | a diagram using specific symbols to show the ancestral relationships for an organism |
| probability | the likely outcome of a cross, not necessarily the true outcome. |
| purebred | an organism that possess identical alleles for the characteristic being considered. |
| sex chromosomes | the X chromosome and the Y chromosome |
