Answer:
Tongue-rolling is dominant, and both parents were heterozygous
Explanation:
Tongue rolling is a type of variation in human beings. When allelic genes are not identical as in Tt, the condition is referred to as heterozygous. An individual with such a genotypic condition is referred to as a heterozygote.
Both parents had a genotype of Tt and they could roll their tongues because T is dominant over the t gene.
T t
T TT Tt
t Tt tt
TT : Tt : tt
1 : 2 : 1
In a heterozygous parent Tt, the chance of producing T gamete from both parents is each 1/2 each. Similarly the chance of forming t gamete is 1/2. Therefore, the chance of gamete T and t fusing to get genotype Tt is 1/2*1/2=1/4.
The ratios of phenotypes are 3/4 will be able to roll the tongue and 1/4 will not be able to roll the tongue.
The mode of inheritance was monohybrid inheritance since one characteristic like tongue-rolling is controlled by a single pair of hereditary factors contributed by both parents.

Black B is dominant over chestnut color b and trotting gait T is dominant over pacing gait t. The answer is 100%. Since all offspring have at least one dominant black hair allele that overwhelms the brown hair allele, all offspring are expected to have black hair.
Phenotype refers to the physical color of a horse's coat or the way genes are expressed. Phenotype II FMF in Familial Mediterranean Fever is the onset of amyloidosis prior to the onset of his FMF with typical attacks or is an isolated finding in members of the FMF family.
White horses have pink skin. White fur mane tail, and hooves. and dark brown eyes. White is the dominant trait W at the white locus. White horse genotype must be heterozygous dominant We. Homozygous dominant because WW is more likely to cause early embryonic loss. Scientists conclude that horses were first domesticated 6,000 years ago in the western part of the Eurasian steppe, in what is now western Ukraine and Kazakhstan.

George is lifting weights. He starts by doing biceps curls
which involves flexing his
elbows. His elbow is able to bend
because the humero-ulnar joint is a hinge
joint. Sam is doing leg presses, extending his knees as he pushes
against the weights. Meanwhile, Jane is doing "lat pulls" by pulling
downward on a weighted bar. This movement involves adduction of her arms.
Her shoulder joint is a ball-and-socket joint, allowing
a wide range of movements.
