Answer #1

ans (1.1)

~ There are two alleles of ADH1A gene segregating in the family. Individuals whose electropherograms exhibit two bands are heterozygous, whereas the individuals whose electropherograms exhibit with single band are homozygous.

ans (1.2)

~ Only the 3rd child is the recombination between the ADH1A and the boneitis- causing locus.

~ As the 1st, 4th , 5th ,6th, and 7th are the children with boneitis , whereas the 2nd and 8th are the children of ADH1A gene segregating  

ans (1.3)

ans (1.5 )

(d) this analysis does not tell us anything about the molecular cause of boneitis.

    Look carefully at the pedigrees below and: 1) indicate whether the transmission appears autosomal or sex-linked 2) indicate whether the transmission appears dominant or recessive 3) provide at least two characteristics for each that support your conclusion. In general, the following characteristics suggest (but do not prove) specific inheritance patterns: Autosomal recessive inheritance: -affected individuals can be born to unaffected parents -if both parents are affected, all children are affected -observable effect of relatedness (consanguinity) -horizontal" inheritance: trait appears at...
