Agapanthus is a dominant, homozygous lethal trait among telorites from the planet teleflora. subjects with this condition love to send flowers. from a group of telorites heterozygous at the agapanthus locus (with two alleles: a = dominant (trait) allele, a = recessive (wild-type) allele), 88% of the telorites have the agapanthus phenotype, and 12% look wild-type. also, true-breeding wild-type telorites (aa genotype) have 0% penetrance. a telorite with the agapanthus phenotype mates with a true-breeding telorite with the wild-type phenotype. one of the f1 children is randomly selected and is mated back to the true-breeding wild-type parent. out of twenty f2 individuals, we observe the following counts: eight f2 individuals have the agapanthus phenotype; twelve f2 individuals have the wild-type phenotype. the genotype of the randomly-selected f1 subject must be:

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
