"The Taco Tongue"
Some people can roll their tongues up into tubular shapes; this is the result of genetics, so a person who can do this can be called a genetic tongue roller (not that there is any important reason to roll up your tongue).
No Flamingos can NOT roll their tongue.
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).
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.

yes. :)

eegra -when you say it you should roll your tongue when you say the r like how spanish people roll their tongue when they say r's.
