Document Summary
Where information in mrna is used to make polypeptides. Mutations: true/false: a mutation must appear in the gametes to be passed on. Ex: down syndrome(trisomy on chromosome 21: define a point-mutation and give an example of one. A mutation that only affects a single nucleotide of nucleic acid. Involve the substitution of one base for another. Ex: sickle cell: define an insertion mutation and give an example of one. Ex: huntington disease: define a deletion mutation and give an example of one. One or few nucleotide base pairs are lost. When someone has two xs and y chromosome, so. Mother, x: describe incomplete dominance:a combined phenotype (ex: red mom and white dad produce pink offspring, describe codominance:when both alleles are shown (ex:red + white= red and white patches, label the images below as polygenic or pleiotropy. Changes in allele frequency due to random factors: explain the founder effect:
