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>

<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.

<span>Animal sources of protein are complete proteins, and some plant foods contain all essential amino acids. Sources of complete animal proteins include milk, yogurt, cheese, meat, poultry, fish, seafood and eggs. Soy protein is a plant-based source of high-quality, complete protein.</span>
Answer:
Proteins seem better suited for storing genetic information because DNA is only made from 4 bases while proteins were made from 20 amino acids, Scientists thought that proteins could code for much greater variety in their amino acid sequence than DNA could in its nucleotide sequence.
