GENÉTICA

Who is known as the father of genetics?

• Charles Darwin

• Isaac Newton

• Gregor Mendel

• Albert Einstein

What are chromosomes?

• Chemical compounds that make up the cell membrane.

• Thread-like structures made of DNA and proteins that carry genetic information.

• Tiny organisms that live in the ocean.

• Structures in the cell that produce energy.

What are Mendel's Laws?

• Mendel's Laws are a collection of mathematical formulas used in genetics.

• Mendel's Laws describe the inheritance of traits in organisms.

• Mendel's Laws are a set of rules for conducting scientific experiments.

• Mendel's Laws explain the process of photosynthesis in plants.

What is a homozygous individual?

• An individual that does not have any alleles for a particular gene.

• An individual that has one allele for a particular gene.

• An individual that has two different alleles for a particular gene.

• An individual that has two identical alleles for a particular gene.

What is a heterozygous individual?

• An organism that has three different alleles for a particular gene.

• An organism that has two different alleles for a particular gene.

• An organism that has no alleles for a particular gene.

• An organism that has two identical alleles for a particular gene.

What are dominant alleles?

• Variations of a gene that are not expressed and have no effect on the phenotype.

• Versions of a gene that are expressed and mask the effects of recessive alleles.

• Versions of a gene that are only expressed in certain individuals.

• Genes that are not inherited from parents but acquired through environmental factors.

What are recessive alleles?

• Genetic variations that are only expressed when an individual has two copies of the allele.

• Genetic variations that are only expressed in certain populations.

• Genetic variations that are always expressed regardless of the number of copies of the allele.

• Genetic variations that are only expressed when an individual has one copy of the allele.
