The gene for hairline shape has two alleles: widow's peak (W) and straight hairline (w). What is the percent probability that on
Alexandra [31]

Answer:

Probability of having a child with genotype Ww is 50%.

Explanation:

This question involves a single gene coding for hairline shape in humans. The allele for widow's peak hairline (W) is dominant over the allele for straight hairline (w). This means that allele W will mask the phenotypic expression of allele w in a heterozygous state.

In a cross between a mother with genotype, Ww and father with genotype, ww, the following gametes will be produced by each parent:

Mother (Ww)- W and w

Father (ww)- w and w

Using these gametes in a punnet square (see attached image), four possible offsprings will be produced with genotypes: Ww, Ww, ww and ww.

Ww(2) : ww(2) or Ww(1) : ww(1)

Hence, 1 out of 2 children produced by the parents will have a genotype Ww, i.e. 1/2. Therefore, the percentage probability is 1/2 × 100= 50%.

Which cell in the skin plays the role of a macrophage
nekit [7.7K]

Macrophages are a type of the White Blood Cells that is a part of the immune system of the body. Macrophages are the first line of defence. They engulf the foreign bodies, foreign particles, cancerous cells and infected cells. They do it by searching for a protein marker on the surface of these foreign bodies. When the marker is absent they attack these bodies by performing phagocytosis.

Langerhans cells present on the skin are specialised macrophages that form the first line of defence.
