How would you designate the structures indicated by the arrows?
A. homologous chromosomes
B. non-homologous chromosomes
C. sister chromatids
D. non-sister chromatids
Homework Answers
Ans:
The structures indicated by the arrows: A. homologus chromosomes.
Explanation:
- There are two categories of chromosomes, sex chromosomes and autosomes ( the chromosomes other than the sex chromosomes).
- Human body cells have 46 chromosomes: 22 homologous pairs of autosomes plus 2 sex chromosomes.
- X and Y are sex chromosomes and remaining 22 are homologus pairs of autosomes.
- Hence correct option is: A. homologus chromosomes.

Part 1 Build a pair of replicated, homologous chromosomes. Use ten beads to create each individual sister chromatid (20 beads per chromosome pair). Two five-holed beads represent each centromere. To do this: a. Start with 20 beads of the same color to create your first sister chromatid pair. Five beads must be snapped together for each of the four different strands. Two strands create the first chromatid, and two strands create the second chromatid, with a 5-holed bead at the...
