Phenotype
Physical look
Genotype
Genes inside that make a physical look
Epistasis
Caused by multiple genes that interact to determine a phenotype
Organisms
Linked by line of descent due to common ancestry
Genetic Code
Found in the molecules of DNA and RNA
Gregor Mendel
Father of genes; studied pea plants to see different phenotypes learned people have dominant and recessive genes
Homozygous
Pair of genes with same recessive or dominant (TT, tt)
Heterozygous
Pair of genes with different recessive or dominant (Tt)
Meiosis
Produces 4 genetically unique daughter cells that are haploid
Basis of sexual reproduction
Meiosis is…
Sexual or asexual reproduction
Eukaryotic organisms use…
Intermediate phenotypes
Occur when incomplete dominance happens
Independent assortment
Alleles for one gene sort independently
Pedigrees
Visual maps pf phenotypes using ancestral relationships
One gene can silence the other
DNA sequences the same but has different outcomes
Epigenetics
Can change with what we eat, smoke, drink, etc
Transgenerational
What your grandparents do can effect you
Multiple Alleles
More than two alleles control a trait
Antigens
Stimulates an immune response when a foreign substance enters the body; produces antibodies
Antibodies
“Soldiers”; destroy foreign substances in the body
RH system
RH is an antigen that is sometimes present on the surface of red blood cells
Agglutination
Antibodies clump (ex. A blood gets B blood infusion causing antibodies to attack)
Sex-linked traits
Determined by genes in the sex chromosomes
Recombination
Chromosomes get unlinked in meiosis
Maternally inherited
99.9% of cell build up, with distinction mitochondrial and chloroplast genes all inherited….
