Homework Answers
the disease is autosomal
recessive.
Ans4- Aa heterozygous
Ans 5- it is Aa i.e heterozygous only, since the father is affected means they has both affected alles, so one of them has to be passes on to the progeny.
Ans 6- could be either homozygous dominant or recessive
Ans 7- option 2 i.e heterozygous because their mother is affected
Ans 8- option 2 is correct.
Hope you find this helpful :)

For each pedigree below determine the most likely mode of
inheritance and label each individual with a genotype. If you know
they have a dominant phenotype, but don’t know the genotype, then
label them with both possibilities. Please use the alleles A and a.
Modes of inheritance for these pedigrees are autosomal dominant or
autosomal recessive. For each pedigree determine if the alternative
mode (not the one you chose) is also possible.
