Question

From the pedigree given in the book on page 184, give the numbers for each individual in the generation and list both their phenotype (normal or colorblind) and their genotype as shown in the example below. Make sure to follow the format below for full credit !!!! (You may want to use example on pg 183 to help you.) If the individual could have two possible phenotypes / genotypes (some in Generation IlI will be this way) list both of them and describe what additional information would be required to definitively determine the genotype and phenotype. i.e. Generation ! Individual 1-"X" phenotype Individual 2-"X phenotype "X" Genotypels) "x" Genotype(s) Generation Il X Individual 1- "X" phenotype Individual 2- "X" phenotype Individual 3.... Genotype(s) "X" Genotype(s) Generation "X" Genotype(s) Individual 1-"X phenotype Individual 2 - "X" phenotypeX" Genotype(s) Individual 3. Individual X- " X" or "Y" Phenotype, ?? phenotype then "X" genotype, f Y phenotype, then "Y" genotype To be able to determine the genotype and phenotype definitively, you would have to... Individual Y..

Explanation / Answer

Colorblindness is an X-linked recessive trait.
(X= dominant, x recessive)

Generation 1:

Generation 2:

Generation 3:

To definitely tell the phenotype and genotype, we need to know whether Gen III individual 4 and individual 6 is a carrier or is affected.

Phenotype Genotype individual 1 Normal Male XY individual 2 Carrier Female Xx
