How does the inheritance of blood groups in humans demonstrate that Mendelian laws are not always followed in heredity?

Nucleic acid certain protein cell membranes certain carbohydrates

Is there any solid scientific evidence that humans have been cloned?

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles
