  • For aliens the allele for a star antennae is dominant to the allele for no star. If a pure dominant alien is crosses with a hybrid alien, what would the genotypes of the offspring be?
  • fertilization
  • In aliens, Q=the allele for a smooth face and q= the allele for face spikes. Give the genotypes for the offspring from Qq x Qq
  • In aliens, Q=the allele for a smooth face and q= the allele for face spikes. Give the phenotype ratio for the offspring.
