Meiosis and Sexual Reproduction

QuestionAnswer
chromosome reduction an event during meiosis during which the original number of chromosomes decreases by half
crossing over the exchange of genetic material between nonsister chromatids of homologous chromosomes during meiosis, which results in new allelic
diploid a cell, individual, or species whose genetic information consists of two homologous sets of chromosome
fertilization the process by which the gametes of two parents unite to form a zygote with a full set of chromosomes
gamete a specialized haploid sex cell, such as a sperm or egg cell, with half the standard number of chromosomes
genetic diversity the difference in the DNA sequences and genes between individuals due to events such as crossing over and mutations
haploid a cell, individual, or species whose genetic information consists of only one set of chromosomes
homologous chromosomes chromosomes that are similar in structure and function but differ in specific genetic instructions such as alleles
independent assortment the process in which homologous chromosomes sort themselves randomly when lining up during metaphase I of meiosis, contributing to genetic variation
meiosis the specialized form of cell division that produces four haploid gametes, or sex cells, from one diploid parent cel
sexual reproduction a form of reproduction in which genetic information in the gametes of two parents is combined to produce genetically unique offspring
zygote a diploid cell that forms when an egg and sperm join during fertilization

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.
