Question

Sex-linked traits do not follow the Mendelian law of inheritance.

True

False

Answer 1

The given statement is true.

There are many types of inheritance, which do not follow the Mendelian law . It includes multiple alleles, gene interactions, linkage with or without crossing over and sex-linked inheritance. Sex-linked traits do not follow the Mendelian law of inheritance. Sex-linked inheritance is an example of non-Mendelian inheritance. Sex-linked inheritance is a type of non-Mendelian inheritance because it opposes Mendel’s first law, which proposes that every trait is always conditioned by two alleles. In non-homologous areas of sex chromosomes, the genotypes of the genes, which contain only one allele (even in the XX karyotype case and one of the X chromosomes is inactive in women).
