3-26 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 separately expressed
codominance
chromosomes 1-44 in a human
autosome
genes that travel on the x chromosome
sex linked
only expressed in the homozygous state
recessive
chromosomes line up randomly during metaphase therefore it is possible for any combination of chromosomes
law of ind assortment
a diagram that shows homologous chromosome pairs
karyotype
the macromolecule that runs your body and expresses your traits
protein
a genotype resulting from the inheritance of two different alleles from ur parents
heterozygous
section of chromosome that codes for a single protein
gene
genes that are likely inherited together due to their physical proximity
linked genes
the physical trait expressed
phenotype
overshadows the other allele in the heterozygous state
dominant
more than 2 versions of a gene ( dominant and rececive)
multiple alleles
condenced genetic material
chromosome
when one gene overshadows another
epistais
a genotype resulting from the inheritance of the same alleles from ur parents
homozygous
at the end of meiosis each gamete formed should only have 1 copy form each homolongous chromosome pair
law of segregation
the macromolecule that has the instructions from making u who u are
DNA
when the heterozygous genotype results in phenotype where the 2 alleles are blended together
incomplete dominance
the actual alleles u inherit
Genotype
the chromosome that desires your sex
Sex chromosomes
the person that has the gene for a trait or disease but doesnt show it
carrier
some versions of genes are dominant over others
Law of dominance
