The ability to roll the tongue inward in humans is determined bya single dominant gene T. This has no practical value, but it isfun to show off at parties. A couple, both of whom can roll theirtongue have a child. True or False:
If the child cannot roll their tongue, their parents must bothbe heterozygous (Tt)
If the child can roll their tongue, their parents must both beheterozygous (Tt)
If the child who cannot roll their tongue grows up to marrysomeone who also cannot roll their tongue, they have a 50% chanceof producing an offspring that can roll their tongue.
If the child who cannot roll their tongue grows up to marrysomeone who is heterozygous for the tongue rolling trait, they havea 50% chance of producing an offspring that can roll theirtongue.
If the child who cannot roll their tongue grows up to marrysomeone who is homozygous for the tongue rolling trait, they have a50% chance of producing an offspring that can roll theirtongue.
