Dominant and recessive genes
Dominant Genes are genes that show they alleles phenotype over the alleles and recessive have to be both genes recessive in order for the genes to be expressed.
Genotype
The Genes that are displayed by a set of letters representing the phenotype.
Phenotype
The physical appearance that is shown by the genotype.
Punnett Squares
A way of calculating the genotypes of offsprings.
Gametes
The genes expressed by parent cells or daughter cells.
Mitosis Vs Meisos
Mitosis is the process of cell division where cells are replaced over and over again. Meiosis is the process of sexual reproduction where the parent cells each give half the necessary components. The difference is that the asexual reproduction produces 2 offspring and sexual reproduction produces 4 offspring. Meiosis also goes through its cycle of PMAT twice.
Pedigrees
A way of showing a person's family tree or line of ancestry that shows certain traits and sex.
Karyotypes
This is a way that each of the chromosomes are aligned so that they are ordered properly and assessed to find out sex, and any mutations.
Sex Linked Chromosomes
XX and XY are Female and Male classification of chromosomes and are the 23rd chromosome of the body. They determine the sex.
Intersex
Certain mutations allow for people to be born as “xxy” meaning they have an extra x chromosome but they are still male. They could also not have enough testosterone to become a male making than female if their chromosomes are XY
