Genotipo

The video explains that recessive alleles are not expressed and thus not visible as external traits. It describes how a person's genotype is determined by genes inherited from both parents, making each human genotype unique, except in the case of identical twins.

What is a characteristic of recessive alleles?

• They are always expressed in the phenotype.

• They are not expressed and thus not visible externally.

• They are only found in identical twins.

• They are dominant over other alleles.

Which statement is true about alleles?

• Alleles are only inherited from one parent.

• Alleles do not affect the genotype.

• Recessive alleles are not expressed externally.

• All alleles are expressed in the phenotype.

How is a person's genotype determined?

• By the environment they live in.

• By their education and experiences.

• By the genes they inherit from both parents.

• By their diet and lifestyle.

Which of the following is true about human genotype?

• It changes with age.

• It is determined by external characteristics.

• It is unique except for identical twins.

• It is the same for all humans.

What makes identical twins unique in terms of genotype?

• They have different genotypes.

• They share the same genotype.

• Their genotype changes over time.

• They have no genotype.
