The genotype that would produce offspring that cannot roll their tongue is 'tt'.
Explicación
## Step 1In this problem, we are dealing with a genetic trait, specifically the ability to roll one's tongue. The trait is dominant, which means that an individual only needs one copy of the dominant allele to exhibit the trait. ## Step 2The dominantT', which stands for the ability to roll one's tongue. The recessive allele is represented by 't', which stands for the inability to roll one's tongue.## Step 3The genotype of an individual is the set of genes they possess. In this case, the genotype is represented by the combination of 'T' and 't'.## Step 4The genotype 'Tt' represents an individual who can roll their tongue. This is because they have one dominant allele ('T') and one recessive allele ('t'). The presence of the dominant allele ('T') allows them to roll their tongue.## Step 5The genotype 'tt' represents an individual who cannot roll their tongue. This is because they have two recessive alleles ('t'). Without the presence of a dominant allele, the recessive trait is expressed, which in this case is the tongue.
