Description
Overview of Genetics Terms
Instructions:
As an introduction to genetics/genomics, write the definitions of the following terms and answer the questions. Submit a copy of your work in the Assignments folder. Please provide at least one reference at the end of the document to show where you found the information for the material. You do not have to reference each term or answer you provide. You should provide at least one overall reference for the assignment citing where you found the information. For example, reference your text or reliable websites such as Genetics Home Reference http://ghr.nlm.nih.gov/
(Note: Genetics Home Reference has merged with MedlinePlus. Genetics Home Reference content now can be found in the “Genetics” section of MedlinePlus.)

Allele –
Chromosome –
Autosome
Sex chromosome
Gene and Genome (Define the terms and explain the difference)
Genotype
Phenotype
Dominant allele (Autosomal dominant and Sex-linked dominant)
Recessive allele (Autosomal recessive and Sex-linked recessive)
*For dominant and recessive: How many copies does it take of each allele to affect the phenotype?
What is meant by the term “obligate carrier”?
