yeasts and molds, both parents contribute to the cytoplasm of the offspring. Their slow growth can be due to a nuclear DNA mutation or a mitochondrial DNA mutation. A recessive nuclear mutation (nn) gives rise to a segregational petite. If most of the mtDNA is missing, a neutral petite (Mn) is formed. If some of the mtDNA is missing, a suppressive petite (Ms) is formed. A complete mtDNA (Mc) allows normal growth to occur, even if the other mtDNAs have missing segments. Mc > Ms > Mn Determine the genotype and phenotype of the F1 in following crosses: a. maternal parent is a heterozygous suppressive petite and the paternal parent is a segregational petite with normal mitochondria. b. maternal parent is heterozygous suppressive petite and the paternal parent is a heterozygous neutral petite.

Question
In yeasts and molds, both parents contribute to the cytoplasm of the offspring. Their slow growth can be due to a nuclear DNA mutation or a mitochondrial DNA mutation.
- A recessive nuclear mutation (nn) gives rise to a segregational petite.
- If most of the mtDNA is missing, a neutral petite (Mn) is formed.
- If some of the mtDNA is missing, a suppressive petite (Ms) is formed.
- A complete mtDNA (Mc) allows normal growth to occur, even if the other mtDNAs have missing segments.
- Mc > Ms > Mn
Determine the genotype and
a. maternal parent is a heterozygous suppressive petite and the paternal parent is a segregational petite with normal mitochondria.
b. maternal parent is heterozygous suppressive petite and the paternal parent is a heterozygous neutral petite.
