If two midgets birth a child, what are the chances it will turn out "normal" sized?

Answer 1

Do you mean midgets or dwarves, since these are very different conditions. And tehre are several different causes of each with as many different patterns of inheritance as you can imagine. For example, someone brought up the Roloffs. The parents have two different types of dwarfism caused by mutations in different genes.

So, basically, garbage in, garbage out. If you don't ask a good question, don;t expect to get an answer!

Answer 2

Some forms of dwarfism (which includes people who used to be referred to as "midgets") are dominant, which means the child will have either a 75% or a 100% chance of having it, depending on whether either parent has two copies of the gene. Other forms are controlled by a variety of genetic factors and may also involve hormonal dysfunction, which means that the child has an elevated risk of dwarfism, but it's not guaranteed.

If the parents are merely extremely short, then the most likely outcome is that their child will be short, but not quite as short as the parents. This is the subject of a practically and historically important statistical phenomenon called "regression to the mean" -- for a person to end up really extremely short (or really extremely tall) requires many different factors to line up just right, and even though many of them are passed on genetically, chances are they won't line up quite as perfectly in the child, leading to a more normal outcome.

Answer 3

There is no way to assess this question on the data given.

What is the cause of dwarfism in the case of each parent.

To give you one scenario, mom and dad could both be dwarves as a result of a deletion on two different spots on the X chromosome- the mom has two copies with the same deletion, the dad has one copy with a different deletion.

We could draw a picture where X=the deletion and ||= normal:
M=x from mom, D=X from Dad.
M: D:
|| ||
X ||
|| X
|| ||

When the body "reads" this, it reads:
||
||
||
||
Which would be normal.

The only way to guarantee dwarfism would be for both parents to have the same kind of dwarfism AND for it to be a kind that worked on a simple mendelian D/R system...most don't.

Answer 4

there is a good chance that it will be a normal size. Havn't you ever seen that tv show, "little poeple in a big world?" I think it is called. They are two midgets with 4 kids. 3 are normal size, one midget. The one that is a midget is a twin. his brother is normal size.

Answer 5

It's Dwarf not midget. Probably 50 50....

Look at the Roloff Family. Out of 5 children only one is a dwarf.

Answer 6

You have a 50/50 chance-midgets (dwarfs) is a genetic defect that may or may not be passed on to any off-spring.

Answer 7

you do a mendel's square or whatever.

it is
dd x dd =dd + dd + dd + dd

so its is probably a 0% percent chance. because im pretty sure dwarfism is a recessive gene. which means that each parent would have to have to recessive genes for the dwarfism to show up. and when you cross those as i did above the only possibility is that all of the children are also dwarfs. but it might not always work out that way.

Answer 8

well dwarfism is a recessive trait so id say the chance of it turning out normal sized would be pretty good, 75% maybe

Answer 9

50/50

Answer 10

I don't know the stats but it is possible look at "Little People Big World" they have 4 kids and only one is a little person and his twin is not little
