U2T4 Meiosis Vocabul

TermDefinition
Asexual Reproduction single parent without the involvement of gametes, resulting in genetically identical offspring.
Sexual Reproduction two parents contribute genetic material to produce offspring with combined traits.
Chromosome A chromosome is a thread-like structure made of DNA and proteins that carries genetic information in the form of genes.
Chromatid one of the two identical copies of a replicated chromosome, joined together at a centromere, which eventually separate during cell division.
Gene segment of DNA that contains the instructions to make a specific protein or RNA molecule.
Allele specific version of a gene that determines variations in a genetic trait.
Meiosis type of cell division that reduces the chromosome number by half to produce gametes (sperm and egg cells) for sexual reproduction, ensuring genetic diversity.
Homologous chromosomes pairs of chromosomes that have the same structure and carry the same types of genes, one inherited from each parent.
Tetrad group or set of four closely associated elements, most commonly referring to the pair of homologous chromosomes aligned together during meiosis.
Crossing over homologous chromosomes exchange portions of their genetic material during meiosis, increasing genetic variation.
Gamete reproductive cell in sexually reproducing organisms that carries half the genetic material of an individual and is essential for sexual reproduction.
Diploid cell or organism that has two complete sets of chromosomes, one from each parent.
Haploid cell or organism that has only one set of chromosomes.

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.
