Question

with these data alone, what can you say about the igf2 genotype of bill sr. and joan?bill jr. and a woman named sara have two children, pat and tim. pat produces only the 60k protein and tim produces only the 50k protein. with the accumulated data, what can you now say about the genotypes of joan and bill sr.?

Answer 1

Without further genetic information, we cannot determine the exact genotypes of Joan and Bill Sr. Inheritance patterns suggest a dominant-recessive relationship for the alleles determining protein size, but additional data is needed to make precise genotype predictions.

Step-by-step explanation:

Considering the scenario involving the family and the production of different sized proteins, we can infer the genotypes of Bill Sr., Joan, and their children.

Since Pat and Tim produce different sized proteins, it is likely that they inherited different alleles from their parents, indicating a heterozygous condition in one or both parents for the IGF2 gene. Based on the information provided, however, we cannot determine the exact genotypes of Joan and Bill Sr. without further genetic information, such as the specific alleles associated with the different protein sizes or more details on how these proteins are inherited.

Without additional data, we can speculate that there is a dominant-recessive relationship concerning the alleles that determine protein size, given the production of singular sized proteins in Pat and Tim. If producing the 60k protein were dominant (let's denote it as 'A') and producing the 50k protein recessive ('a'), and considering the children are producing only one type of protein, we might infer that Pat is 'AA' or 'Aa', and Tim is 'aa'. Nevertheless, these are hypotheses and would need to be validated with further genetic testing.
