Widow's peak is a dominant trait. This means that if a person inherits one copy of the gene for a widow's peak from either parent, they will have a widow's peak.
Yes, you are correct.
because that persons grandma or grandpa or one of their past realatives could have had that trait
You wouldn't see a recessive trait if an individual has one dominant and one recessive allele for that trait. In this case, the dominant allele's phenotype will be expressed, masking the recessive trait. The recessive trait would only be visible if an individual has two copies of the recessive allele.
Yes, if a person expresses a recessive trait, their genotype must be homozygous recessive for that trait. This means that they have two copies of the recessive allele, one from each parent. If they were heterozygous they would not display the trait.

In genetics, the phenotype represents the physical characteristic/trait. For example brown eyes is a phenotype. When referring to alleles which are alternative forms of a gene, it is the dominant allele that is represented physically. For example if brown eyes are a dominant trait, then they would be represented physically in the genotypes BB and Bb.

You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
The outward appearance of a trait refers to how that trait is physically expressed or manifested in an individual or organism. This could include characteristics such as eye color, plant height, or fur texture that are visible and observable.
When the allele that codes for the dominant trait is expressed in the genome.
no
You wouldn't see a recessive trait if an individual has one dominant and one recessive allele for that trait. In this case, the dominant allele's phenotype will be expressed, masking the recessive trait. The recessive trait would only be visible if an individual has two copies of the recessive allele.
Physically, if you can see, you can physically look forward. However, if you physically can see, it does not necessarily mean you have a mind, therefore mentally you may not be able to look ahead. On the other hand, if you are blind physically, there is no way to see ahead in a physical sense. This does not mean you can not mentally see or look forward.
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
phenotypeThe physical appearance of a trait is called a phenotype, not to be confused with a genotype( which is your genetic makeup) The way I remember is phenotype and physical both start with a p, and genotype and genetic both start with a g.
