Question
Choose any and all of the following statements below that are true.
-Genes that are found in mitochondria have no biological consequence.
-The only type of extranuclear inheritance that occurs in plants is mediated by chloroplasts.
-Mitochondrial DNA is circular, and this is why it is maternally inherited.
-A person can inherit more than one genotype of mitochondria from their mother.
-In human cells, mitochondrial DNA is circular and nuclear DNA is linear
-Mitochondria, chlorplasts and Golgi Bodies can all pass on genetic information through extranuclear inheritance.
-In humans, some diseases caused by extranuclear inheritance are inherited from the male parent.
Explanation / Answer
Genes that are found in mitochondria have no biological consequence: False, because mitochondrial genes are maternally inherited.
The only type of extranuclear inheritance that occurs in plants is mediated by chloroplasts: False, because extranuclear inheritance is also mediated by mitochondrial genes and hence, almost all eukaryotic cells carryout extra nuclear inheritance.
Mitochondrial DNA is circular, and this is why it is maternally inherited: True, because the mitochondrial genome is of varying size and is maternally inherited.
A person can inherit more than one genotype of mitochondria from their mother: True because alleles of autosomal chromosomes are inherited from mother.
-In human cells, mitochondrial DNA is circular and nuclear DNA is linear: True.
Mitochondria, chlorplasts and Golgi Bodies can all pass on genetic information through extranuclear inheritance: False. only mitochondria and chloroplasts are involved in extranuclear inheritance.
In humans, some diseases caused by extranuclear inheritance are inherited from the male parent: False. because, extranuclear inheritance occurs from mother to offspring and not from father.
