Exam 6: Extranuclear Inheritance, Imprinting, and Maternal Effect

If a maternal effect gene has a dominant allele,and a recessive allele then a mother with a dominant phenotype will always produce offspring that have a dominant phenotype as well.

R and r represent dominant and recessive alleles,respectively,for a gene that is imprinted. Imprinting of the allele occurs in the male and the allele is silenced when it is imprinted. Which mating would result in a ratio of 1:1 of dominant and recessive phenotypes in the offspring?

Heteroplasmy is associated with inheritance patterns involving ________.

What is a disease associated with extranuclear inheritance?

Erasure of methylation occurs in the

Where does erasure and imprinting occur?

Which of the following is true regarding mt genomes?

Which mating of four-o'clock plants would produce progeny that were either green,variegated,or white if the color variation is due to a mutation in a chloroplast gene?

An example of genomic imprinting is

A nurse cell is a cell that

What is thought to be the origin of mitochondria and chloroplasts?

The inheritance of leaf pigmentation in the four-o'clock plant Mirabilis jalapa is an example of ________.

mtDNA contains all of the genes necessary for the complete function of mitochondrial metabolism.

What is the type of inheritance that is based on a reversible modification of genomic DNA that results in the alleles of only one parent being transcriptionally active?

What are some diseases associated with imprinting?

Who is largely responsible for proposing the endosymbiosis theory?
