Phenotype

The video explains the concept of phenotype, which is the observable expression of genes. It uses the example of eye color to illustrate how an individual's genotype, containing alleles for both blue and brown eyes, results in a phenotype of brown eyes due to the expression of the dominant allele.

What is the term used to describe the observable expression of genes?

• Allele

• Chromosome

• Genotype

• Phenotype

In the context of eye color, what does the phenotype represent?

• The combination of alleles

• The genetic makeup of an individual

• The recessive trait

• The observable eye color

If an individual has alleles for both blue and brown eyes, which eye color will be expressed if brown is dominant?

• Hazel

• Brown

• Green

• Blue

What determines the phenotype of an individual?

• The environment

• The dominant allele

• The recessive allele

• The number of chromosomes

Which of the following is an example of a phenotype?

• A DNA sequence

• A pair of alleles

• A genetic mutation

• Brown eyes
