Sexual reproduction

TermDefinition
Chromosomes Pairs of chromosomes that have genes for the same traits arranged in the same order are called homologous chromosomes.
Phase of Meiosis 1 In the first phase, duplicated chromosomes condense and thicken. Homologous chromosomes come together and form pairs.
Phase of Meiosis 2 In the second phase, the two cells formed during this stage go through a second division of the nucleus and the cytoplasm.
Maintaining Diploid Cell Diploid cells have pairs of chromosomes, meiosis helps to maintain diploid cells in offspring by making haploid sex cells.
Creating Haploid Cells The result of meiosis is haploid sex cells, this helps maintain the correct number of chromosomes in each generation of offspring.
Genetic Variation Genetic variation exists among humans, it occurs in all oranisms that reproduce sexually.
Selective Breeding Farmers started to choose which traits they wanted by selecting certain plants to reproduce and grow.
Fission It begins when a prokaryote's DNA molecule is copied, each copy attaches to the

Fission It begins when a prokaryote's DNA molecule is copied, each copy attaches to the cell membrane.
Mitotic Cell Division Many unicellular eukaryotes reproduce by mitotic cell division. In this type of asexual reproduction, an organism forms two offspring through mitosis and cell division.
Budding A new organism grows by mitosis and cell division on the body of its parent, when the bud becomes large enough, it can break from the parent and live on its own.
Animal Regeneration Another type of asexual reproduction, regeneration, occurs when an offspring grows from a piece of its parent, the regenerate a new organism varies greatly among animals.
Vegetative Reproduction Plants can also reproduce asexually in a process similar to regeneration, it is a form of asexual reproduction in which offspring grow from a part of a parent plant.
Cloning A type of asexual reproduction performed in a laboratory that produces identical individals from a cell or form a cluster of cell taken from a multicellular organism.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
