Rod like structures tat store and transmit geneic info: genes segments of dna, autosomes most chromosomes, sex chromosomes x and y. Paterns of inheritance (eg. dominant-recessive, codominance, x-linked: dominant-recessive only 1 allele (dominant one) afects child"s characterisics. Heterozygous individuals are carriers: modiier gene enhance or dilute the efects of other genes, codominance both alleles inluence the child"s characterisics, x-linked harmful allele is carried on the x chromosome.
