Basic Human Genetics
one of two paired chromosomes, one from each parent, that carries genes for a specific trait at the same location
cell with half the number of chromosomes as a diploid cell
haploid sex cell, formed during meiosis, that can be combined with another haploid sex cell and produce a diploid fertilized egg
reduction division process, occurring only in reproductive cells, in which one diploid cell produces four haploid cells that are not genetically identical.
exchange of chromosomal segments between a pair of homologous chromosmes during Prophase I of Meiosis
functional unit that controls inherited trait expression that is passed on from one generation to another
alternative form that a single gene may have for a particular trait
most common, shown most common, appears the most, masks the recessive trait
hidden or masked; less common
organism with 2 of the smae alleles for a specific trait
organism with 2 different alleles for a specific trait
an organism's allele pairs
observable characterisitic that is expressed as a result of an allele pair.
the chances of getting a specific result
characteristic controlled by genes on the X chromosome
individual heterozygous for a recessive disorder
X or Y chromosome; paired sex chromosmes determine an individual's gender
chromsome that is not a sex chromosome
organism heterozygous for a specific trait
