The correct answer is that variable number repeats are used in DNA tests; they have hundreds of possible lengths. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called, melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.

Why is mating between blood relatives discouraged from a genetic perspective?
algol [13]

Inbreeding is simply defined as the mating of relatives. It is a mating system in which individuals carry alleles that originated from a common ancestor. Inbreeding is considered a problem in humans because inbreeding increases the chances of receiving a deleterious recessive allele inherited from a common ancestor.

Which function of the nephron includes the movement of fluid from the blood into bowman's capsule?
iragen [17]

Bowman’s capsule it can also be called glomerular capsule. Bowman’s capsule it is a cup-like sack which is found at the beginning of tubular component of a nephron in the kidney of a mammalian which performs the first step of filtration of changing blood into the urine. A glomerulus is the enclosed in the sac.

Bowman’s capsule is where fluids from blood in the glomerulus are collected and further processed to nephron to form urine through a process ultrafiltration. Bowman’s capsule named after Sir William Bowman. Bowman’s capsule has some layers inside.

The outer one is a parietal layer which is a single layer of simple squamous epithelium and doesn’t function infiltration.The other layer is a visceral barrier. It lies immediately above the glomerular basement membrane which is made of podocytes and beneath it, we have glomerular capillaries.

Filtration barrier is the function of fluid from the blood into Bowman's capsule. The barrier allows passage of small molecules, ions, and water from the bloodstream into Bowman’s space and it also prevents passage of negatively charged protein, for example, albumin.
