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.

For the trait that is coded by a recessive allele to be expressed, the must be homology, which means that an offspring has to inherit that recessive allele from both its parents.
A dominant allele will dominate over the recessive allele, so for the trait coded by a dominant allele to be expressed, the offspring only needs to inherit the allele from one of its parents.
For example: "R" is brown eyes, "r" is blue eyes.
Now you get one R from each of your parents.
RR (homozygote) = brown eyes
Rr (heterozygote) = brown eyes
rr (homozygote) = blue eyes
The foods must be cooled to below 4 °C
Answer:
Explanation:
ells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis, which chloroplasts are needed for, which yields oxygen and glucose, plants need to break down the glucose and they use cell respiration to do this, which happens in the mitochondria.
