Question
If the trait is recessive, then what is the genotype of person #1?
12. what is the genotype of person #2?
13. what is the genotype of person #3?
14. what is the genotype of person #4?
15. what is the genotype of person #5?
16. what is the genotype of person #6?
17. what is the genotype of person #7?
18. what is the genotype of person #8?
19. what is the genotype of person #9?
20. what is the genotype of person #10?
21. what is the genotype of person #11?
22. Is it possible for this to be a recessive trait? (Do the genotypes you reconstructed make sense?)
23. Autosomal dominant traits:
Not all genetic defects are recessive. Some are dominant, although the incidence of these genes tends to be rare, since they are not passed on very frequently. The pedigree chart from the first exercise is reproduced below. Repeat the exercise, but this time assume that the trait is dominant. Therefore, each person who has the trait must have at least one dominant allele, while unaffected individuals must have two recessive alleles.
If the trait is dominant, then what is the genotype of person #1?
24. What is the genotype of person #2?
25. What is the genotype of person #3?
26. What is the genotype of person #4?
27. What is the genotype of person #5?
28. What is the genotype of person #6?
29. What is the genotype of person #7?
30. What is the genotype of person #8?
31. Is it possible for this trait to be dominant? (Do the genotypes you reconstructed make sense?)
32. Can a dominant trait skip generations (not be expressed in every generation, but only every other, or more infrequently)?
