Human Development:
Abnormal Genes and Chromosomes, and Teratogens Human development involves the growth of a zygote to maturity in a gradual process. A series of complex changes occurs within human bodies as development takes place. For instance, cells multiply either through meiosis or mitosis. The genetic makeup of cells also replicates. Normally, chromosomes will be separated to allow for replication of genes within cells. This process is very important during development. However, some abnormalities occur to genes and chromosomes due to teratogens. Teratogens are substances that interfere with the normal fetus or embryo growth and development, whereby they lead to their ...
