Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
Hydrogen ions are actively transported out of the mitochondrial matrix.
Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix.
answer is polygenic inheritance
The dominant RR (red) and recessive rr (white). The color pink seems to be an intermediary between the dominant and recessive parent. Thus a heterozygote (Rr) that contains both a dominant and recessive gene will have a pink color.
Answer:
c. RrMm x RrMm
Explanation:
A dihybrid genotype is the one that is heterozygous for two genes. Hence, a dihybrid cross is a cross between two individuals that are hybrid for alleles of two different loci.
Among the given examples, the cross RrMm x RrMm is a dihybrid cross. Here, both given genotypes are heterozygous or hybrid for two loci (both genotypes have one dominant and one recessive allele for both the genes under study, R and r; M and m).
This cross explains the inheritance of two loci or two genetic traits. Hence, it is an example of dihybrid cross.
