Question

Would someone please check my answer to this Genotype problem?

Refer to the pedigree below. Individuals who are shaded have a rare autosomal recessive disorder. Those who are not shaded have the dominant phenotype. A is Dominant allele, a is recessive allele Fill in probability function for the genotype of EACH INDIVIDUAL Give all probabilities as fractions that are simplified to the lowest value Type your fractions in #/# format without spaces. For example, one-half should be typed as 1/2. Place a zero in each space that does not have a number. Individual I-3 is genotype O AA+ 1 Aa+ O aa Individual 11-4 is genotype 1/3 AA 2/3 Aa Q aa Individual l-5 is genotype FAA-Aa + F aa Individual ll-l is genotype-% AA + Aa-aa Individual 11-5 is genotype-AA + F Aa + ??? Individual 11-6 is genotype |-1/3 AA + ?-2/3 Aa . T aa Individual 111-1 is genotype l 112 AA + 1 1/2 Aa + aa Individual IlI-2 is genotype aa

Explanation / Answer

i-3 :correct
ii-4 :AA-1/3; Aa-2/3 ; aa-0, correct
i-5 : correct
ii- 1: In a pedigree person from outside the family is to be cosidered as completely normal, unless it is evident in the pedigree. Hence the II-1 is assumed to be AA. so probability is =
AA-1; Aa- 1/2; aa-0

II-5:correct
II-6: correct
III -1: AA-1/2; Aa - 1/2

III-2: Correct
