Answer:
Steps in correct sequence:
B) – D) – A) – E) –C) – F)
Explanation:
Cell-mediated immunity is a particular adaptive immune response. This type of immune response fight against intracellular infections such as viruses, some bacteria, fungi, and Plasmodium. Cell- mediated immune response is activated by TH1 cells.

D) T cells with specific receptors recognize the antigen.
A) Several cycles of mitosis occur.
E) T cells differentiate into cytotoxic T cells or T memory cells.
C) Cytotoxic T cells migrate to focus of infection.
F) Cytotoxic T cells release perforin and/or lymphotoxin.
About the question: You will find the pedigree in the attached files
Answer:
Autosomal recessive inheritance
Explanation:
Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.
Let us assume that the diallelic autosomal gene has a dominant allele L that expresses the normal phenotype and the recessive allele l that expresses the altered phenotype. The pedigree would be as shown in the attached files.
To interpret the pedigree, remember that
- Squares represent males
- Circles represent females
- Empty figures express normal/healthy/not affected individuals
- Solid black figures represent affected individuals
