Variation of Traits
Biology
| Question | Answer |
|---|---|
| Discovered one chromosome was shorter than its homologous pair, and he experimented with fruit flies. | Thomas Morgan |
| Traits on the sex chromosome, which are grouped together with either an XX or an XY. | sex linkage |
| Genes found on the X. | X-linked genes |
| Genes found on the Y. | Y-linked genes |
| Not a sex chromosome. | autosome |
| Genes located on one chromosome. | linkage group |
| Diagram that shows linear sequence of genes on a chromosome. | chromosome map |
| The exchange of genes with the same segment from a different homologous chromosome during meiosis. | crossing over |
| Mutations in the organisms germ cell. | germ-cell mutation |
| Mutation in the organisms body cells. | somatic mutation |
| Mutation that cause death, usually before birth. | lethal mutation |
| Abnormalities that affect chromosomes. | chromosomal abnormalities |
| Loss of a piece of a chromosome due to chromosomal breakage. | deletion |
| A chromosome mutation in which a chromosomal segment breaks off and the reattaches in reverse orientation to the same chromosome. | inversion |
| A chromosome mutation in which a chromosome piece breaks off and reattaches to another non-homologous chromosome. | translation |
| Is the failure of a chromosome to separate from its homologous during meiosis. | nondisjunction |
| A family record that shows how a trait is inherited over several generations. | pedigree |
| Disease that has a genetic basis. | genetic diorder |
| A trait controlled by a single gene. | single-allele traits |
| A trait controlled by three or more alleles of the same gene that codes for a single trait. | multiple-allele traits |
| Recessive X-linked disorder in which an individual can not distinguish between certain colors. | colorblindness |
| Recessive X-linked trait that impairs the ability of the blood to clot following a cut or bruise. | hemophilia |
| X-linked form of muscular dystrophy that weakens and progressively destroys muscle tissue. | duchenne muscular dystrophy |
| A condition in a diploid cell which one chromosome of one pair is missing. | monosomy |
| A condition where an individual has an extra chromosome in any of the chromosome pairs. | trisomy |
| Has an extra X chromosome. 47, XXY, in every male births. | klinefelter syndrome |
| 47 XXY (non disabilities) in every male births. | XXY syndrome |
| XXX (non-disabilities) no physical or mental differences. | triple X syndrome |
| Very short-lived, less than 1 year old, a lot of development issues. The legs are sideways. | Edward's syndrome |
| Very short-lived, less than 1 year old, a lot of development problems. Doesn't have a face. | Patau syndrome |
