Answer:
Patterns of inheritance in humans include:
Autosomal dominant or recessive inheritance
X-linked dominant or recessive inheritance
Mitochondrial inheritance
Y-linked
Explanation:
Mitochondrial inheritance is the type of inheritance which arises from the mothers only. A person tends to inherit its mitochondrial DNA only from the mother and not from the father.
Autosomal inheritance is the pattern of inheritance seen by the alleles of genes present on the autosomal chromosomes.
X- linked inheritance is the pattern of inheritance depicted by the genes on the X chromosomes.
Y-linked inheritance is attributed to the pattern of inheritance depicted by the genes on the Y- chromosomes. However, very few genes are present on this chromosome.
<span>It
is important that antibodies have a symmetrical quaternary structure to create
two identical binding sites for antigens. An antibody is a relatively large
protein having a Y-shape. Plasma cells produce antibodies which are then used
by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody
is able to recognize the antigen of the pathogen. It binds with it either to
neutralize it directly or “tag” the microbe for future attack by other parts of
the immune system. </span>
Sarah is correct because genetic diversity occurs over along period of time
