Ragos y herencia: cromosomas

Gregor Mendel's work on genetics was initially overlooked but was rediscovered in the early 20th century, forming the foundation of modern genetics. Scientists confirmed Mendel's findings on trait inheritance and identified genes within chromosomes as the carriers of genetic information. Chromosomes, found in every cell, are composed of numerous genes and are crucial in determining an organism's traits.

What was the significance of the rediscovery of Mendel's work in the early 20th century?

• It introduced the concept of DNA sequencing.

• It disproved the theory of evolution.

• It formed the basis of modern genetics.

• It led to the development of new agricultural techniques.

What did scientists agree upon regarding Mendel's conclusions?

• Traits are inherited from parents.

• Traits are acquired through environmental factors.

• Traits are random and unpredictable.

• Traits are influenced by diet.

Where are the genes responsible for traits located?

• In the cell membrane.

• In the cytoplasm.

• In chromosomes within cells.

• In the cell wall.

What do chromosomes contain?

• Water and minerals.

• Many genes.

• Proteins and lipids.

• Vitamins and enzymes.

What role do chromosomes play in an organism?

• They control the organism's traits.

• They provide energy to the organism.

• They protect the organism from diseases.

• They help in the digestion of food.
