A man with blood type A and a woman of blood type B have a baby girl of blood type O. The man sues his wife for divorce, on the grounds that it is not possible for the baby to be theirs (since the blood type is not A, B. or AB). Evaluate the lawsuit on the basis of genetics (A, B alleles are co-dominant over the recessive O allele).
IA = A allele IB = B allele iO = O allele
Label each true or false

A. AT =C/G
B. Quantitative geneticists are interested in identifying the number of genes
contributing to a phenotype
C.Inbreeding depression is associated with decreased heterozygosity
Polydactyly is a congenital physical anomaly in in
humans, dogs, cats; and having supernumerary fingers or
toes. If it is an autosomal dominant trait, when is a genotype of a person that shows normal
phenotype?
a. heterozygous recessive
b. heterozygous dominant
c. homozygous recessive
d. homozygous dominant
