Answer 1

Mach the following to the corresponding terms: When a faulty copy of a single gene affects a wide range of body systems, this is called _pleiotropy___. When symptom severity depends on the number of mitochondria with mutations that an individual inherits this is due to _Heteroplasmy____. More males suffer from X-linked recessive conditions because they are __Hemizygous__ for these traits. When geese that consume high amounts of lead shot develop liver disease, this is an example of a __Phenocopy___. When the alleles of genes are always inherited as a package because they are located close to one another, we call this _Linkage____. When a woman has some patches of skin with sweat glands and some patches without them, this is due to __Penetrance__. _Heritability____ estimates the proportion of phenotypic variation for a trait that is due to genetic differences. A Labrador retriever with a homozygous dominant genotype should be black, but is golden due to a mutant E allele. Epistatis.
