Question

A husband & wife have freckles (both of them), however their daughter does not. How & why is this the case? In your own words.

Answer 1

the hormones combing from the parents have resulted in the formation of an offspring without freckles.one possible explanation is that father has large freckles while mother has less promonent freckles.the combination has led to the formation of their child without freckles..

converting this into more simpler terms the +ve genes of father &the -ve genes of mother have neutralized and have led to the creation of a child without freckles

Answer 2

I'm only 15, and I'm just trying to explain it from what I think I remember from Biology class, so don't take my information as 100% true, necessarily. My memory's not perfect. =]

But I think that freckles are a dominant gene, and maybe both the parents have one gene for freckles and one without, each. Their daughter happened to get one gene without freckles from each of them, probably. If I'm right, there's a 25% chance that that would happen.

I hope that helps explain it a bit. =]

Answer 3

mabe it might be that they are like there cousen or aunty you never no

Answer 4

It is true that freckles are genetic, but they also take time to appear.  How old is the daughter?  Freckles may not start to appear on a person until they reach their teenage years!  There are other factors involved too.  Many times freckles don't appear until after years of sun exposure, and with all the steps people are taking these days to prevent sunburn, it is possible that their daughter has been protected from too much sun with sunscreen, and hats, etc.

In rare cases the kid will inherit a different skin type from it's parents, but that's uncommon.  I've also seen kids with freckles where neither parent ever had any at all.

The tendency to get freckles is more complex than just simple dominant and recessive genes though, as many people think.  This is supported by the fact that ALL skin types can develop freckles!  I personally have observed this for myself, and I definitely notice freckles, because I think girls with freckles are HOT, so my "radar" is always on the lookout for the Freckled Hotties!

Answer 5

It all has to do with gene's if you look up dominant and recessive traits that should help you understand it a little more.

Answer 6

Okay, let's start with the grandparents on the husband's side. If the grandpa has freckles, but the grandma does not, the husband has inheirted the freckles from the grandpa.

It could be the same for the wife. She might have inheirted the freckles from her father, or her mother.

But in each of the husband and wife, they carry a dominant gene for freckles, and a recessive gene for no freckles. (Dominant genes are almost always shown in children, but there is a 25% chance that they will not be shown in grandchildren. Recessive genes are almost never shown in children, but are still available for the grandchildren.)

So the husband's and wife's daughter does not have freckles because she had a 25% chance not to have freckles.

It's all really confusing at first, but as you learn more about it, it gets easier. Hope I helped.

Answer 7

i think its because the daughter has the recessuve gene of having freckles....so her daughters/sons will be the ones to have the freckles..and you didnt mention if she was the frist or second child....

Answer 8

Even though both parents were carrying the genes for freckles, the genes for an even covering of melanin (the coloring in skin responsible for skin tone & freckles) were dominant, so that's what came out in the daughter.

Answer 9

crossing genes from family

Answer 10

this is so because when the child most lickkley got on of the grandparents traits..meaning either grandma or grandpa from the moms side and grandma or grandpa from the dads side.

Answer 11

The parents both had a dominant and a recessive gene. Where the dominant gene for freckles was manifested in both parents, the child was the 1/4 of possible outcome to have no freckles (the other 3/4 possibilities would have freckles).

Answer 12

A child doesn't have to look anything like their parents. Later down the road they may start favoring their parents or someone else in the family.

Answer 13

there are basically 2 types of genes.

they are active and recessive.

it depends on the prominance of these genes!

in this case the recessive genes are prominant.
