Heredity Vocab Twsy Flashcards
When several genes influence a trait
Polygenic inheritance
A version of a gene
Allele
When the heterozygous genotype results in a phenotype where both alleles are fully and seperately expressed
Codominance
Chromosomes 1-44 in a human
Autosomes
Only expressed in homozygous state
Recessive
Genes that travel on the X chromosome
Sex-linked
Chromosomes line up randomly during metaphase therefore it is possible for any combination of chromosomes to be passed on from parent to offspring
Law of ind. assortment
A d diagram that shows homologous chromosome pairs
Karyotype
The molecule that runs your body and expresses your traits
Protein
A genotype resulting from the inheritance of two different alleles from your parents
Heterozygous
Section of a chromosome that codes for a single protein
Gene
Genes that are likely inherited tighter due to proximity
Linked genes
Overshadows the other allele in the heterozygous state
Dominant
The physical trait expressed
Phenotype
More than two versions of a gene ( more than just a dominant and recessive)
Multiple alleles
Condensed genetic material
Chromosome
When one gene over shadows another
Epistasis
At the end of meiosis each gamete formed only has one copy from each homologous chromosome pair
Law of segregation
A genotype resulting from the inheritance of the same alleles from your parents
Homozygous
The macromolecule that has instructions for making you who you are
DNA
When the heterozygous genotype results in a phenotype whether the two alleles are blended together
Incomplete dominance
The actual ALLeles you inherit
Genotype
The chromosomes that determine your sex
Sex chromosomes
A person that has the gene for a trait or disease but doesn’t show it
Carrier
