While I can't say for certain, I can tell you some things that are responsible for freckles other than heredity. The sun is probably the #1 reason for freckles and heredity plays the biggest role in how many freckles are produced. The issue has to do with our body's production of melanin and how that melanin (which incidentally protects us from the sun's UV rays) respondes to sunlight.
And while this is not quite scientific, I believe that when we get freckles (most of us freckle as we age regardless of heredity), it is a by product of our body trying to ward off the effects of the sun. There are products out there that can diminish freckling and most of them deal with somehow inhibiting the melanin's response to skin inflammation and things like the sun. For more information, you should check into hyperpigmentation and other skin problems that are the direct influence of melanin production.
What else can I help you with?
Are freckles dominant recessive or dominant dominant?
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
Are freckles a genetic trait?
Yes, freckles are a genetic trait. The presence of freckles is influenced by genetics, particularly genes associated with the production and distribution of melanin in the skin. However, other factors such as sun exposure can also play a role in the development of freckles.
If dad has freckles and is homozygous and mom has freckles and is heterozygous what phenotypes and genotypes can you expect their offspring?
Alright, I suppose I will do your homework for you.. Here is your punnet square: F F F FF FF f Ff ff Therefore, 3/4, or 75%, offspring will have the phenotype of having freckles, and 1/4, or 25% will have the phenotype of no freckles. And 2/4, or 50%, of the offspring will have the genotype for homozygous for freckles, 1/4, or 25%, of the offspring will carry a heterozygous trait for freckles, and 1/4, or 25%, of the offspring will have the phenotype for homozygous no freckles.
Are Freckles are a physical trait that is transmitted by a recessive gene?
Yes, freckles are a physical trait that can be determined by genetic factors. The development of freckles is influenced by a combination of genetic predisposition and exposure to sunlight, rather than being solely determined by a single recessive gene.
What country has the most freckles?
There is no specific country that is known to have the most freckles. Freckles are a result of genetic factors and sun exposure, so they can be found in people of various nationalities around the world.
A man and a woman are both heterozygous Freckles are dominant over no freckles What are the chances their children will have freckles?
There is a 75% chance that their children will have freckles and a 25% chance that their children will not have freckles. This is because both parents are carriers of the freckles allele and can pass it on to their offspring.
