Document Summary
Every person starts life as a single cell, called a zygote. Single cell that is formed from the fusing of two gametes, a sperm and an ovum. All living things are made up of dna. All living things are composed of cells that promote growth and sustain. Each molecule of dna is called a chromosome life according to instructions in their molecules of dna. Contain units of instructions called genes , with each gene located on a particular chromosome. Each gamete sperm in a man and ovum in a woman has only 23. If the match between the two genes is exact (as it usually is since most. Allele : any of the possible forms of a gene. Genes that have various alleles are polymorphic (literally, many. If the allele of a particular gene from the father differs from the forms ) allele of that gene from the mother, the person is said to be heterozygous (literally, other zygote )
