No Flamingos can NOT roll their tongue.
They are all extrinsic muscles of the tongue, used for crude movement.

If the individuals can't roll their tongue, then the child won't be able to roll it's tongue. If they can roll their tongue, then the child will be able to roll it's tongue. it just depends.
Being able to roll your tongue is a genetic trait controlled by a single gene with two alleles. If you can roll your tongue, you are likely to have inherited the dominant allele for tongue rolling. If you cannot roll your tongue, you likely have inherited the recessive allele.
The ability to roll the tongue is determined by a dominant gene (T) and a recessive gene (t). A man who can roll his tongue would have the genotype Tt or TT, with the phenotype of being able to roll his tongue.

Being able to roll your tongue is dominant, not being able to is recessive. Therefore, if you can roll your tongue, you have either a homozygous dominant gene for being able to roll your tongue, or a heterozygous gene. If you cannot, then you have a homozygous recessive gene.
If one parent is heterozygous for the tongue rolling gene (Tt) and the other parent cannot roll their tongue (tt), the chances of their children being tongue rollers (Tt) is 50%. The other 50% chance is that the children will not be able to roll their tongue (tt).
Different people inherit different muscles. Some folks can, some can't. There is some evidence that it may even be genetic.
The Tongue is actually a collection of muscles, both internal and external.The external muscles reposition the tongue, while the internal muscles alter the shape of the tongue for talking and swallowing.A list of both external and internal muscles can be found at the Wikipedia article listed below.If you would like to learn about keeping your tongue muscles in shape, you look at the list of tongue twisters found in the harvestall link below.
The ability to roll your tongue is a genetically inherited trait. Some people can do it, and others can't. If you can roll your tongue, it simply means that you have inherited that trait. If you can't, then you lack it. It's genetic, and out of your control.
