Humans have a gene, "T" that is involved in muscle formation of the tongue. Individuals with the one allele can roll their tongu
zhuklara [117]

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.

iris [78.8K]

Answer:

Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system changes to relieve the stress.

Explanation:

This principle shows that when we change a system in equilibrium, it will seek to acquire a new state that nullifies this disturbance. Thus, there is a displacement of equilibrium, that is, a search for a new equilibrium situation, favoring one of the senses of the reaction. If it favors the direct reaction, with formation of more product, we say that the equilibrium has shifted to the right. However, it is said that it shifted to the left if the reverse reaction was favored, with formation of reagents.
