A) They follow the same principles as Mendel's model, with no differences.

B) They involve only a single gene, just like Mendel's model.

C) They deviate from Mendel's model by involving multiple genes, gene interactions, or non-Mendelian inheritance patterns.

D) They are not related to genetics and inheritance.

Final answer:

Patterns of inheritance can differ from Mendel's model through incomplete dominance, codominance, multiple gene inheritance, and sex-linked inheritance.

Step-by-step explanation:

PATTERNS OF INHERITANCE THAT DIFFER FROM MENDEL'S MODEL:

Incomplete Dominance: In this pattern, neither allele is dominant over the other, resulting in a blending of traits. For example, when red flowers are crossed with white flowers and produce pink flowers.

Codominance: In this pattern, both alleles are expressed equally in heterozygous individuals, resulting in the expression of both traits. For example, in humans, the ABO blood group system.

Multiple Gene Inheritance: Some traits are influenced by multiple genes, such as height or skin color.

Sex-Linked Inheritance: Certain traits are carried on the sex chromosomes and are more commonly expressed in one gender. For example, hemophilia is a sex-linked disorder carried on the X chromosome.
