Get started for freeDrosophila may be monosomic for chromosome \(4,\) yet remain fertile. Contrast the \(\mathrm{F}_{1}\) and \(\mathrm{F}_{2}\) results of the following crosses involving the recessive chromosome 4 trait, bent bristles: (a) monosomic IV, bent bristles \(\times\) diploid, normal bristles; (b) monosomic IV, normal bristles \(\times\) diploid, bent bristles.
Define these pairs of terms, and distinguish between them. aneuploidy/euploidy monosomy/trisomy Patau syndrome/Edwards syndrome autopolyploidy/allopolyploidy autotetraploid/amphidiploid paracentric inversion/pericentric inversion
Human adult hemoglobin is a tetramer containing two alpha (a) and two beta ( \(\beta\) ) polypeptide chains. The a gene cluster on chromosome 16 and the \(\beta\) gene cluster on chromosome 11 share amino acid similarities such that 61 of the amino acids of the \(\alpha\) -globin polypeptide (141 amino acids long) are shared in identical sequence with the \(\beta\) -globin polypeptide \((146\) amino acids long. How might one explain the existence of two polypeptides with partially shared function and structure on two different chromosomes?
What evidence indicates that humans with aneuploid karyotypes occur at conception but are usually inviable?
What evidence suggests that Down syndrome is more often the result of nondisjunction during oogenesis rather than during spermatogenesis?
