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 10% 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 only observe nineteen wild-type phenotype and one agapanthus phenotype.
the genotype of the randomly-selected f1 subject must be:
a. aab. aa. c. we cannot say with certainty. we need to perform a chi-square goodness of fit test. d. aa. e. aa or aa.
