Good morning/afternoon! 1/23/17 Explain how non-disjunction mutations occur. Based on the picture to the left is the patient a male or female? How are karyotypes organized? Analyzing the karyotype does this person have a non-disjunction mutation? If so, trisomy or monosomy for what chromosome?

Dominant vs. Recessive aa AA or Aa Versus

What does Dominant and Recessive Mean? Allele= different form of a gene (provided from mom & dad) Dominant= masks effect of recessive gene Recessive= only shown when homozygous recessive

Basic Vocabulary Phenotype: Physical appearance What you see Genotype: Genetic make-up What you cannot see

A dominant allele produces a dominant phenotype A recessive allele produces a recessive phenotype. The individual must have two copies, one from each parent.  Light colored eyes are normally caused by the coupling of recessive alleles.

Homozygous vs. Heterozygous Homo = Same or Similar Hetero = Different #Equality17 Heterozygous Dominant Homozygous Dominant Homozygous Recessive
