Meiosis Ch 13

QuestionAnswer
asexual reproduction a single individual is the sole parent
sexual reproduction two parents give rise to one offspring (2:1)
during sexual reproduction meiosis reshuffles the existing genetic information to create mew genetic combinations
mutation the only way that genetic variation can arise from asexual reproduction
clone a group of genetically identical individuals resulting from asexual reproduction
gametes meiosis results in the formation of haploid reproductive cells
zygote two of these cells join by fertilization to form during sexual reproduction
fertilization the union of two gametes to produce a zygote
if the diploid number for an animal cell is 20 how many chromosomes will a gamete of this animal have 10
animal one multicellular stage that is diploid
plant two multicellular stages, one diploid, the other haploid
fungus one multicellular stage that is haploid
what three unique events take place during meiosis 1. crossing over during Prophase I 2. alignment of homologous chromosomes during Metaphase I 3. separation of homologous chromosomes during Anaphase I
what does meiosis require requires two rounds of cell division
what are the results of meiosis results in four haploid daughter cells
are daughter cells genetically or physically different from each other genetically
does DNA replicate between meiosis I and meiosis II NO
how many rounds of cell division does meiosis require 2
during anaphase of meiosis, sister chromatids are pulled apart. during anaphase I of meiosis, homologous chromosomes are pulled apart. TRUE OR FALSE TRUE
list three ways that sexual reproduction results in genetic variation (genetically different offspring) 1. crossing over 2. independent assortment of homologous chromosomes 3. random 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.
