举一反三
- What is the reason that linked genes are inherited together? A: The number of genes in a cell is greater than the number of chromosomes. B: Genes align that way during metaphase 1. C: They are located on the same chromosome. D: Alleles are paired.
- Which is correct about the red-green colorblind in humans? A: loss of L or M cone genes on the X chromosome B: gain of S cone genes on the X chromosome C: loss of L or M cone genes on the Y chromosome D: gain of S cone genes on the Y chromosome
- 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
- Tumor suppressor genes encode proteins that normally restrain cell division. Mutation in one or more of these genes can lead to tumor formation.
- Linked genes
