WebGregor Mendel's principles of heredity, observed through patterns of inheritance in pea plants, form the basis of modern genetics. Mendel proposed that traits were specified by "heritable elements" called genes. Genes come in different versions, or alleles, with dominant alleles being expressed over recessive alleles. WebSEX-LINKED TRAITS Name:_____ Because the “X” chromosome is three times the size of the “Y” chromosome, it contains many more genes than the “Y” chromosome. Therefore, sex-linked characteristics tend to be controlled by genes on the “X” chromosome. Because men only have one “X” chromosome, they tend to show these sex-linked characteristics …
