Question #1e6f7
1 Answer
Let's use the letter A for the normal condition and a for albinism as symbols for the alleles. George's genotype is aa, Mary's is Aa, Frances's is aa, Jack's is Aa, Anne's is Aa.
Explanation:
George has the condition so he must have the aa as a genotype since it is a recessive trait and only occurs when it is homozygous.
Same is for Frances. Since Mary is normal and she's Frances's mother so she must be a carrier with a genotype Aa.Now comes jack who must be carrying at least one a from his mom, and since his daughter is normal then his genotype should have at least one normal allele, because his daughter is normal and her mom is albino, so the daughter must have taken the normal allele from Jack. His genotype is Aa. Anne is normal but her mom's genotype is aa, so she must be Aa.
