Genetics How it works

Gregor Mendel was known as the father of genetics.
Genetics is the study of heredity which informs you upon what genes you do or do not have. Genes are made up of two alleles, alleles are sub units of heredity. One Gene is dominant and one of the genes are recessive. An organism has two descriptions of itself, One being the genotype and the other being the Phenotype.
An organism has two descriptions of itself. One, being the genotype and the other being the Phenotype. Genotype is what specific genes are in the organism. Phenotype is the actual description of the organism.
Although the dominate traits normally shine through, the recessive ones can appear in future generations. This is called Mendel's Principle Of Dominance.Incomplete dominance is where multiple phenotypes are see in a blended form. Codominance is where the multiple phenotypes are shown in spotty ways. Ex Snakeskin would have different spots.
Punnet squares are tools that scientists use to show all the potential phenotypes and genotypes that an offspring can display, being based on the parents genes. punnet squares can be used to cross 3,4, or even more traits at a time.
Humans have 23 chromosomes. Chromosomes 1-22 are called autonomes and chromosome 23 is called the sex chromosome. This chromosome determines the sex of the child.The Karyotype is the organism's chromosomal profile.
The epigenome is the outer layer of genetic info around your dna. It is considered to be the punctuation marks of your genetic code
The carrier is the one who could possibly pass on a genetic allele to their offspring. Sex-linked trait is passed between the X and Y traits. It is more common among males than females.
Pedigree charts is how you can trace your ancestry. This is used to find different traits through your family line. It is traced by affect family members rather than all of them.
There are two different types of genes. Homozygous and Heterozygous. Homozygous is where the gene has two of the same alleles, Whereas Heterozygous has one dominant and recessive trait.
The four blood types are A, B, AB, and O. When someone uses a punnet square to figure out a persons blood type, this is called blood typing. another part of your blood is the Rhesus factor, The majority of the global population id RH+ with only around 15 percent of the population being RH-.
