| Question | Answer |
|---|---|
| Segregation of alleles in game formation occurs in Anaphase I of meiosis | True |
| An allele is the physical location of a gene along a chromosome | False, LOCUS |
| Chromosomes 1-22 in humans are known as autosomes | True |
| At sexual maturity human ovaries and testes produce diploid gametes by meiosis | False, HAPLOID |
| Homologous chromosomes each have the same particular genes/genetic info but alleles may differ | True |
| Haploid gametes can divide to form diploid cells | False, CAN'T DIVIDE |
| Meiosis is gamete formation via separation of homologous chromosomes | True |
| The human X and Y chromosomes... | include genes that determine an individual's sex |
| The karyotype of one species of primate has 48 chromosomes. In a particular female, cell division goes wrong and she produces some of her eggs with an extra chromosome (25). The most probable source of this error would be a mistake in: | Either Anaphase I or II |
| ___ --> ___ --> ___ represents the change of chromosome number in a cell as it goes through Meiosis I and II | 2n --> 4n --> 2n |
