Basic Genetics: The Genome & Chromosomes from Chapter 8 / Lesson 1 117K A person's eye color, height, hair color, etc. are all attributes of one's genetics. Learn about basic genetics, including genomes, chromosomes, homologous chromosomes, gametes, and diploid complements. Related...

Polysomy isa condition where there is more than one copy of the chromosome relative to the normal. Trisomy (2N+1) and tetrasomy (2N+2) are examples of polysomy. Trisomy is a polysomy characterized by an extra copy of a particular chromosome. What does Polysomy mean? [ pŏl′ē-sō′mē...
Alleles are the versions of the gene that the organism receives from its parents. Each organism will get one allele from each parent. Each parent contributes half of the chromosomes for the offspring, and their chromosomes match up to provide the two alleles needed for each gene. There are...
are made up of chromatin. Chromatin made up of the threads of DNA forms the structure of chromosomes. The DNA gets condensed to form chromosomes. Genes are the segments of DNA. The code for proteins. This means chromosomes are made up of DNA which contains many genes in the...
Gametes are haploid, which means they each have only one copy of the 23 chromosomes that make up the human genome. (The word “haploid”comes to us from the ancient Greekhaploos, or “single, simple, once”.) When the haploid egg and sperm cells unite, they eventually create a person ...

Eye colour and colour perception are excellent examples to use when teaching genetics as they encompass not simply the basic Mendelian genetics of dominant, recessive and X-linked disorders, but also many of the new concepts such as non-allelic diseases, polygenic disease, phenocopies, genome-wide...
