Abortion is the murder of an innocent human life

The moment that a human sperm cell (the male gamete) fuses with a human egg cell (the female gamete) in what is known as “fertilization”, a single-cell, human diploid zygote, containing all of the genetic information necessary to proceed seamlessly (if uninterrupted by accident, disease, genetic defect, or external intervention) in the human developmental process (i.e. zygote, embryo, fetus, infant, toddler, child, adolescent, adult) is produced. Let us consider the following to help clarify some of that terminology:

“Gamete”
• Gametes, commonly referred to as an organism's reproductive cells or sex cells, are haploid cells (which means that they contain one set of chromosomes). In most humans, a gamete contains 23 chromosomes, or rather, half of a human’s genetic information (typically, each human has 46 chromosomes).

"Single-cell, human diploid zygote"
• The cell is the basic structural and functional unit of life forms. Only things that are living (or were living at one point or another) are composed of cells.
• A human is a member of the species "Homo sapiens". The fertilization of a human egg cell by a human sperm cell cannot produce anything other than a human cell.
• A diploid cell is a cell that contains two complete sets of chromosomes (23 chromosomes from the human male gamete and 23 chromosomes from the human female gamete). All of the cell types in our body, are diploid, except for gametes, which are haploid.
• A zygote is an organism within the animal kingdom, which is in the first stage of its developmental process. A zygote's genome (all of the genetic information of an organism) is a combination of the DNA in its parent’s gametes, and therefore, a zygote is a genetically distinct organism from its parents.
