The following method illustrates the gamete formation of the heterozygous individual but the same steps can be applied to the formation of gametes in a homozygous individual.



First, determine the genotype of the individual. In this case we have a heterozygous individual. If M represents the dominant allele, which of the following would represent an individual heterozygous for the number of air bladders?




Which of the images below show the homologous chromosomes for this individual as they would appear just before meiosis?








Which of the images below show the cells produced at the end of meiosis I for the above chromosomes?





Which of the images below show the cells produced at the end of meiosis II for the above chromosomes?





Repeat the above reasoning for the homozygous dominant individual.
