17. Explain why males have a greater chance of having hemophilia than females. Be specific.

18. What type of genotype will children have for a trait if both parents are homozygous recessive for it?

19. If an offspring shows a phenotype that is intermediate between the phenotypes of the parents, what is this type of inheritance?

20. What type of inheritance is demonstrated by human blood types?

21. If one parent is type AB blood type and the other parent is type B blood type, could they have a child that is O blood type?

25. What is the genotypic ratio from a monohybrid cross?

26. Use the Punnett square application to determine the answers for questions 26 and 27 in the following simple monohybrid cross. (If you don't understand how to fill in a Punnett square, you can use google for help.): A man who is homozygous recessive for attached earlobes (ee) has children with a woman who is heterozygous for attached/unattached earlobes (Ee). Use E for unattached lobes and e for attached lobes. Identify the alleles that would be entered for the female and for the male.

27. What percentage of the offspring are expected to show the recessive phenotype?

28. Use the Punnett square application to determine the answers for questions 28, 29 and 30 for the following simple monohybrid cross. (If you don't understand how to fill in a Punnett square, you can use google for help.): A man who is heterozygous for cleft chin has children with a woman who is also heterozygous for cleft chin. Use C for the cleft chin allele and c for the non-clefted chin allele. The allele for cleft chin is dominant. Identify the alleles for the female and the male.

29. What percentage of the offspring are expected to show the dominant phenotype?

30. What percentage of the offspring are expected to have a heterozygous genotype?
