Answer:

A pH indicator is able to tell what level of pH the substance is at. It can tell how acidic a substance is. If a substance has more hydrogen ions than hydroxide ions then it is acidic. If it has more hydroxide ions that hydrogen ions it is an akaline. the acidic scale is from 0 to 14. lower numbers means more acidic and higher numbers means it is an alkaline.

Explanation:

pH stands for potential Hydrogen.

This pedigree supports the fact that widow's peak is due to a dominant allele, because if it were due to a recessive allele and
sammy [17]

This pedigree supports the fact that widow's peak is due to a dominant allele because if it were due to a recessive allele and both parents show the recessive phenotype, then <u>all of the offspring would have a widow's peak.</u>

<u></u>

<h3>What is the widow Peak gene?</h3>

A widow's peak is a distinctive, V-shaped hairline that tends to run in families. Despite the myths, it's probably no more significant than other genetic traits such as curly hair or a cleft chin. Some people prefer to downplay their widow's peak and some want to show it off.

The following genetic disorders are linked to the widow's peak: Arskog syndrome is a rare genetic condition that primarily affects men. Children with Aarskog syndrome have short stature in addition to deformities of the face, limbs, and genitalia.

There is a 75% likelihood that any of the offspring of parents who are heterozygous (Ww) will have a widow's peak.
