- Extranuclear inheritance often correlates with maternal inheritance. Even so, paternal leakage may occur. What is paternal leakage? If a cross produced 200 offspring and the rate ofmitochondrial paternal leakage was 3%, how many offspringwould be expected to contain paternal mitochondria?arrow_forwardWhat kind of inheritance pattern is this?arrow_forwardDescribe some of the key features of cytoplasmic inheritance.

Give a specific example.arrow_forwardWhich of the following describes the difference between genetic maternal effect and cytoplasmic inheritance? O Progeny from a Genetic Maternal Effect cross express the phenotype of their mother's genotype, while progeny from a cytoplasmic inheritance cross share a genotype and phenotype of their mother. Progeny from a Genetic Maternal Effect cross have a phenotype that reflects their own genotype, while progeny from a cytoplasmic inheritance cross share a genotype and phenotype with their mother. Progeny from a Genetic Maternal Effect cross have the same genotype as their mother, while progeny from a Cytoplasmic Inheritance cross do not. There is no difference.arrow_forwardWhat feature(s) of this pedigree indicate(s) dominant inheritance?arrow_forward
- Genetic maternal effect is often seen in mammals. For example, research shows that the maternal genotype influences adult body size in mice. Why might these types of genetic effects be more common in mammals than in other organisms such as fishes, amphibians, or reptiles?arrow_forwardIn most animals, a larger amount of cytoplasm is carried by the egg then by sperm. Similarly, the egg in plants carries more cytoplasm than the pollen. How could this difference affect the expression of inherited traits (a) dependent on nuclear chromosomal genes and (b) dependent on extranuclear genes.arrow_forwardWhy are lethal dominant genes much more rare than lethal recessive genes?arrow_forward
