Non-Mendalian Traits

non-mendalian patterns

follow different mechanisms of inheritance and has neither dominant nor recessive traits

codominance

two dominant alleles are present and both will be expressed

incomplete dominance

recessive allele combines with another recessive allele

• codominance makes both alleles have 50/50 shown

• incomplete dominance makes a new result show

difference in results between codominance and incomplete dominance

lethal genes

combination of alleles will result to death of the carrier

multiple alleles

when more than two alleles exist of a certain character

agglutinogens

name for A and B antigens

agglutinin

substance that makes particles coagulate

agglutinogens

forms agglutinin

polygenic inheritance

traits that are controlled by two or more genes

polygens

genes involved in polygenic inheritance

sex-linked inheritance

inheritance of genes located in the sex chromosome

sex-influenced inheritance

autosomal traits whose expression of dominance is affected by the sex of the individual

pleiotropy

condition when one gene causes several effects in various organs of the body
