a person who does not suffer from a recessive genetic debilitation, but who carries an allele for it that can be passed along to offspring.
genetic conditions in which a single faulty allele can cause damage, even when a second, functional allele exists.
Autosomal dominant disorder
simply meaning a dominant genetic disorder caused by a faulty allele that lies on an autosomal chromosome.
ex. Huntington disease
familial history intended to track genetic conditions. Diagram can detirmin wheater a condition is dominant or recessive, and X-linked or autosomal and probability for future inheritance.
condition in which one or more entire sets of chromosomes has been added to teh genome of a diploid organism. Uncomon, egg doesn't servive
is one in which an organism has either more or fewer chromosomes than normally exist in its species' full set. Gain or loss of a single chromosome. Very common, and mostly unrecognized (unnoticed miscarigs). Ebryos that seruvive aneuplody that have additional chromosomes 13,18, or 21 ex. Down syndrom - gain of additional chrom 21(3 copies of chrom 21)
In somatic cells can happen at any age that lead to cancer.
a cause of aneuploidy. A failrue of homologous chromosomes or sister chromatids to separate during meiosis. Can occur either in meiosis I or II.
