Question

In humans, freckles are controlled mainly by the MC1R gene, and they show a dominant pattern of inheritance. Use F to represent the allele for freckles, and f to represent the allele for no freckles. If a male and a female who both carry one allele for freckles and one allele for no freckles (Ff) have a child, what would be the likelihood that the child would have freckles?

Answer 1

The likelihood that the child would have freckles is 50%. Freckles are dense Melaninized cell clusters that are especially noticeable on fair-skinned people. Instead of having more melanin-producing cells, or melanocytes, freckles contain melanocytes that create excessive amounts of melanin granules, which alters the color of the outer skin cells.

As a result, freckles differ from moles and lentigines, which are brought on by a concentration of melanocytes in a specific region. All shades of skin can get freckles. The six Fitzpatrick skin types are most prevalent on skin tones 1 and 2, which are typically associated with people from North Europe.
