B: Genes align that way during metaphase 1.
C: They are located on the same chromosome.
D: Alleles are paired.

举一反三
- The chromosome theory of inheritance states that A: All are correct B: chromosomes are made of DN C: genes are located on chromosomes. D: alleles of a gene segregate during cell division.
- If two genes from a parent cell are on the same chromosome, which of the following best explains why the daughter cells may not have the same alleles as the parent for both genes? A: they are linked genes B: they are unlinked genes C: crossing-over D: genetic mutation
- Linked<br/>genes are A: found<br/>on the same chromosome B: found<br/>in the same nucleus C: found<br/>only on sex chromosomes D: joined<br/>by a centromere
- Most of the X-lined genes in humans are expressed in equal amounts between males and females because A: only one of the two X chromosomes is active in each cell in the females. B: X-linked genes on the X chromosome in males are expressed two-fold higher than in females. C: only one X chromosome is kept after fertilization. D: Half of the RNA transcripts from X chromosomes in female cells are degraded after transcription.
- Genes come in different versions called: A: alleles B: loci C: genetypes D: chromosomes E: genomes
