yes, often

in autosomal dominant, describe male/female distribution

equally likely

in autosomal dominant, do parent need to have for children to have?

yes, affected children need at least one affected parent

in autosomal dominant, do carriers exist

no, both heterozygous and homozygous have trait

in autosomal dominant, do traits skip generations

no they dont

in x-linked recessive, describe male/female distribution

males are more affected than females

in x-linked recessive, describe relationship between father/son

father can never pass down trait to son

in x-linked recessive, do traits skip?

yes

in x-linked dominant, describe male/female distribution

equal chance

in x-linked dominant, describe father/son relationship

father never passes down trait to son

in x-linked dominant, describe father/daughter relationship

affcted father always passes down traight to daughter

in x-linked dominant, does trait skip generations

no

difference between pedigrees for sproadic and familial cancers

sporadic is not hereditary so will no be passed down so only 1 or 2 ppl have it. familial is when a lot of family has it.

in autosomal recessive, describe male/female distribution

equal change of being affected

in autosomal recessive, do parent need to have for children to have?

no, affected offspring often have unaffected (heterozygous) paretns
