🗑
|
||||
| show | autosomes
🗑
|
||||
| T or F : Gametes are diploid so that when fertilization occurs the resulting zygote will have the chracteristic number of chromosomes for that species | show 🗑
|
||||
| The protein disk that binds to chromosomes together is called a? | show 🗑
|
||||
| show | chromatin
🗑
|

|
||||
| show | Interphase, G1, S phase, M phase, prophase, metaphase, anaphase, telophase, cytokinesis.
🗑
|
||||
| The two halfs of chromosomes held together by a centromere are called? | show 🗑
|
||||
| show | 2n
🗑
|
||||
| show | 1n
🗑
|
||||
| show | diploid
🗑
|
||||
| show | 16
🗑
|
||||
| show | usually just one- prokaryotes do not have a nucleus and usually only have a single, circular strand of the DNA molecule that serves as a chromosome
🗑
|
||||
| Is interphase part of mitosis? | show 🗑
|
||||
| show | metaphase
🗑
|
||||
| As a result of mitosis, each daughter cell recieves only half the number of chromosomes in the origional cell? | show 🗑
|
||||
| show | Teleophase
🗑
|
||||
| Metaphase II is part of mitosis? | show 🗑
|
||||
| show | No- the (I) indicaties meiosisI
🗑
|
||||
| show | no- prokaryotic cells divide by binary fission
🗑
|
||||
| show | prophase I
🗑
|
||||
| show | 4
🗑
|
||||
| How many egg cells are produced from oogenesis? | show 🗑
|
||||
| show | cell plate
🗑
|
||||
| show | 6
🗑
|
||||
| Which cells undergo meiosis? | show 🗑
|
||||
| The first cell resulting from the fusion of gametes is called? | show 🗑
|
||||
| show | Mitosis = nuclear division and meiosis is chromosome reduction in two stages MI and MII. Essentially, meiosis is just like mitosis except for crossing over and synapsis of chromosomes in prophase I. At the end of meiosis I there is two haploid cells and
🗑
|
||||
| Is DNA copied prior to meiosis II? | show 🗑
|
||||
| show | Homologous pairs of chromosomes include one chromosome from each parent. Sister chromatids are identical copies of DNA held together by a centromere.
🗑
|
||||
| show | yes... leads to two diploid cells .
🗑
|
||||
| show | Homologous pairs of chromosomes include one chromosome from each parent. Sister chromatids are identical copies of DNA held together by a centromere.
🗑
|
||||
| show | T

| An individuals karyotype indicated three chromosomes at position 23 XXY. What is the sex of this individual? | show 🗑
|
||||
| show | testes
🗑
|
||||
| What organ does oogenesis take place in/ | show 🗑
|
||||
| show | Female
🗑
|
||||
| show | male- if a y chromosome is present, the sex is male by definition.
🗑
|
||||
| Is binary fission asexual or sexual reproduction | show 🗑
