The mother dragon is heterozygous for the wing gene ( Ww ) and the horn gene ( Hh ). The father is homozygous recessive for the wing gene ( ww ) and the horn gene ( hh ). What phenotypic traits will each parent have? (Phenotypic traits are the observable bodily characteristics.) Draw the appropriate characteristics for each parent. Mother Father 1
Review of Inheritance of Single Genes Draw a Punnett Square to show the inheritance of the horn alleles for a mating between this mother and father. On average, what fraction of the baby dragons will have big horns? Predictions of Inheritance of Two Genes on Different Chromosomes To predict the inheritance of the wing and horn genes, you first need to determine the genotypes of the eggs produced by the heterozygous ( WwHh ) mother dragon and the sperm produced by the homozygous ( wwhh ) father dragon. Considering both the wing and horn genes, what different genotypes of eggs could the heterozygous mother dragon produce? Use the figure below to answer this question.
Two equally probable chromosome arrangements in Meiosis I: or Meiosis II: or Gametes or with Genotypes: or What genotypes or genotype of sperm can the homozygous ( wwhh ) father dragon produce? Draw a diagram to show how meiosis would occur in the father (like the mother diagram given), starting with a diploid cell ready to undergo meiosis 1 and ending with four haploid sperm.
The next step in predicting the inheritance of the wing and horn genes is to predict the outcome of fertilization between these eggs and sperm.
