Sister chromatids are which of the following? a. Found right after a cell divides. b. Formed when chromatids separate during cell division. c. Unique to prokaryotes. d. Tightly linked together at a centromere. e. Made only of DNA - Answer-d. Tightly linked together at a centromere. Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you re...

Allele correct answer: different versions of the same gene; example: A and a, or A and A' (for codominant traits) Anaphase I correct answer: chromosomes separate from their homologue and move toward opposite ends of the cell Anaphase II correct answer: chromosomes separate and begin to move toward opposite ends of cell Codominant correct answer: neither allele is completely dominant; heterozygous is an intermediate version (A and A') Dihybrid correct answer: 4x4 Punnett square...
