Huntingtons
Both parents show the same phenotype for a trait. They have a child with a different phenotype. The genotype of that child is____
Homozygous Recessive
more than two alleles (or versions) of the gene
ex: blood types

Does not require energy
does not synthesis of new molecule.

How could you tell a disease is inherited as an x-linked recessive trait in a pedigree?
Mostly males have the disease/trait

contains carbon, oxygen, and hydrogen atoms: ratio of hydrogen atoms to oxygen atoms is 2:1. function-
