Sometimes, a mother who is affected with a mitochondrial disease will have an unaffected child. Which of the following could explain this observation?Select all that apply.A. The phenotype could be affected by nuclear genes, which could differ among children.B. One or more of the children could inherit the majority of their mitochondria from an unaffected father.C. The affected mother could be heteroplasmic.D. Environmental factors (such as taking antibiotics) could affect expression of the phenotype.
  • A. The phenotype could be affected by nuclear genes, which could differ among children.C. The affected mother could be heteroplasmic.D. Environmental factors (such as taking antibiotics) could affect expression of the phenotype.
  • If one parent is a translocation heterozygote for chromosomes 14/21, a child born to this parent is as likely to have Down syndrome as he is to be normal.
  • tumor-suppressor genes
  • Suppress the replication of mutant mitochondria and favor the replication of normal mitochondria.
