22. Question: In cats, yellow fur is dominant over white fur
Question: In cats, yellow fur is dominant over white fur. A heterozygous cat is mated with a white cat. The possible genotypes of that offspring are:

23. Answer: Yy or yy

24. Question
Define what a genotype is.

25. Answer
A genotype is the description of the combination of alleles for a specific trait.

26. Question
What do shaded in shapes on a pedigree mean?

27. Answer
The shaded in shapes represent where the trait is expressed in that family or who is “affected” by the trait.

28. Question
Using the pedigree below, tell me the genotype of person II-6. The shaded in genotype is recessive.

29. Answer Aa

30. Question
Define the term phenotype.

31. Answer
An organism’s physical traits. Its appearance.

32. Question Is it possible for person 8 or 9 to be homozygous? Explain.
***Remember the trait is recessive.

33. Answer
No, because 2 of their children have the trait and that means they must each carry one recessive gene.

34. Question
Explain the law of dominance.

35. Answer
Whenever there is a dominant allele in a genotype, the phenotype will always be dominant over an recessive alleles.
