1 Meiosis, Karyotypes, Nondisjunction, Fertilization, & Differentitation Test Review
2 Vocab Meiosis Karyotypes & Nondisjunction Fertilization Miscellaneous
3 Vocab: 10 What are homologous chromosomes? ANSWER
4 Vocab: 10 - Answer Same size and shape, and contain the same genes (may be different versions thus slightly different DNA)
5 Vocab: 20 What is a tetrad? (use the correct vocabulary) ANSWER
6 Vocab: 20 - Answer A tetrad is a pair of homologous chromosomes (these match up during Prophase I of meiosis)
7 Vocab: 30 ANSWER
8 Homologous chromosomes are not necessarily identical, they carry the same genes they could be different versions of the gene. Vocab: 30 - Answer
9 Vocab: 40 Is this cell haploid or diploid? Somatic or gamete? 2n or n? ANSWER
10 Vocab: 40 - Answer The cell is diploid (it has pairs of homologous chromosomes), thus it would be a somatic cell (such as a skin cell or muscle cell any body cell), and is 2n
11 Vocab: 50 What is cell differentiation? ANSWER
12 Vocab: 50 - Answer The process by which cells are directed to specialize into various different tissues.
13 Meiosis : 10 What stage of Meiosis is this? ANSWER
14 Meiosis : 10 - Answer Metaphase I of Meiosis (notice the formation of tetrads pairs of homologous chromosomes)
15 Meiosis : 20 How are homologous chromosomes matched up and in what phase of meiosis do they pair up? ANSWER
16 Meiosis : 20 - Answer They pair up by same size (and they contain the same type of genes). During Prophase I they pair up.
17 Meiosis : 30 What stage of meiosis is this in? What event is happening which increases variation in offspring? ANSWER
18 Meiosis : 30 - Answer Prophase I Crossing over occurs and increases genetic variation in the daughter cells
19 Meiosis : 40 What event in this stage leads to variation? ANSWER
20 Meiosis : 40 - Answer Independent Assortment (during Metaphase I) leads to genetic variation in the daughter cells.
21
22 Meiosis : 50 If a cell starts with 20 chromatids at the beginning of Meiosis, how many chromosomes will be in one of the haploid cells at the end of Meiosis? ANSWER
23 Meiosis : 50 - Answer If there are 20 chromatids then the cell is starting with 10 chromosomes. After meiosis is complete, each haploid daughter cell will have 5 chromosomes each
24 Karyotypes & Non-disjunction : 10 How are the chromosomes arranged in a karyotype? (be specific!) ANSWER
25 Karyotypes & Non-disjunction : 10 - Answer Chromosomes are arranged in homologous pairs from BIGGEST TO SMALLEST with the sex chromosomes at the very end.
26 Karyotypes & Non-disjunction : 20 Is this from a 2n or n cell? How can you tell? ANSWER
27 Karyotypes & Non-disjunction : 20 - Answer This karyotype come from a cell that is 2n. You can tell it is a diploid (2n) cell because the chromosomes are in their homologous pairs.
28 Karyotypes & Non-disjunction : 30 In a human, how many autosomes are there? How many sex chromosomes? ANSWER
29 Karyotypes & Non-disjunction : 30 - Answer 44 autosomes (or 22 pairs) 2 sex chromosomes (or 1 pair)
30 Karyotypes & Non-disjunction : What 40 aneuploidy would this individual have? What disorder is this called? ANSWER
31 Karyotypes & Non-disjunction : 40 - Answer Aneuploidy XXY (has an extra X chromosome) Klinefelter s Syndrome
32 Karyotypes & Non-disjunction : 50 How does a non-disjunction in Anaphase I compare to Anaphase II? ANSWER
33 Karyotypes & Non-disjunction : 50 - Answer Anaphase I Homologous chromosomes (tetrads) fail to separate Results in aneuploidy in all daughter cells Anaphase II Double stranded chromosome (sister chromatids) fail to separate Results in aneuploidy in half of the daughter cells Anaphase I Anaphase II
34 Fertilization : 10 What is a fertilized egg called? (a fertilized egg results from an egg and sperm fusing together what is this new cell called?) ANSWER
35 Fertilization : 10 - Answer A zygote!
36 Fertilization : 20 What are sex cells called? And where are they made? ANSWER
37 Fertilization : 20 - Answer Sex cells (egg and sperm cells) are called gametes. Egg cells made in ovaries, sperm cells made in testes
38 Fertilization : 30 What is the correct sequence that describes the development of a baby? Baby, Embryo, Fertilization, Fetus, Zygote ANSWER
39 Fertilization : 30 - Answer Fertilization, Zygote, Embryo, Fetus, Baby
40 Fertilization : 40 How many chromosomes are in a human gamete? How many chromosomes are there in a human zygote? ANSWER
41 Fertilization : 40 - Answer 23 chromosomes are in a human gamete 46 chromosomes are in a human zygote
42 Fertilization : 50 Why is it important that both gametes are haploid? ANSWER
43 Fertilization : 50 - Answer Both gametes are haploid because when they come together they will make a fertilized diploid cell (thus RESTORING the original amount of chromosomes)
44 Miscellaneous: 10 True or False: Homologous chromosomes are exactly identical. ANSWER
45 Miscellaneous: 10 - Answer False, homologous chromosomes contain the same types of genes, but they may be different versions. Thus the sequence of DNA nucleotides could be different!
46 Miscellaneous: 20 What kind of aneuploidy does a person that have Turner s syndrome have? 2n-1 or 2n+1 How do you know? ANSWER
47 Miscellaneous: 20 - Answer 2n-1 They are missing one of their X chromosomes (in every single cell)
48 Miscellaneous: 30 Would this cell be considered n or 2n? ANSWER
49 Miscellaneous: 30 - Answer 2n It has homologous pairs of chromosomes
50 Miscellaneous: 40 If the cell starts with 40 chromosomes at the beginning of Meiosis, how many chromosomes will be in one of the haploid cells at the end of Meiosis? ANSWER
51 Miscellaneous: 40 - Answer 20 chromosomes (the number is halved in meiosis)
52 Miscellaneous: 50 How is spermatogenesis different from oogenesis? (definition + difference in the END RESULT) ANSWER
53 Miscellaneous: 50 - Answer Spermatogenesis (production of sperm) produces 4 functional haploid sperm cells at the end of meiosis, Oogenesis (production of eggs) produces 1 functional haploid egg cell and 3 haploid polar bodes that later disintegrate.
