Notes on Inheritance and Reproduction

These flashcards cover key concepts from the lecture notes on inheritance, reproduction, and the process of meiosis.

What is the main difference between sexual and asexual reproduction?

Sexual reproduction involves two parents and results in genetically different offspring, while asexual reproduction involves one parent and produces genetically identical offspring.

What process forms gametes?

Meiosis is the cell division process that produces gametes.

Where does meiosis occur in an organism?

Meiosis occurs in reproductive organs.

What is the outcome of meiosis in terms of chromosome number?

Meiosis results in cells with half the original chromosome number, leading to genetic variation.

What are gametes in animals and plants?

In animals, gametes are sperm and egg cells; in plants, gametes include pollen grains (male) and egg cells (female).

Why is genetic variation important for a species?

Genetic variation helps species adapt and evolve, ensuring survival during fertilization processes.

What happens during the reduction stage of meiosis?

During the reduction stage, original cells copy their chromosomes and then undergo separation of similar chromosomes to create new cells with half the chromosome number.
