Earlobes may be free or attached, as shown in the illustrations below. The type of earlobe a person has is genetically determined. The allele for free earlobes (E) is dominant, while the allele for attached earlobes (e) is recessive. The inheritance of the earlobe trait can be traced over several generations using a family tree called a pedigree. A pedigree for the earlobe trait is shown below. (QUESTION) If female #3 and male #4 were to have another child, what would be the probability of that child having attached earlobes? answers:
1/4

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
