11.4 wkbk 16-27 KEY
16. Prophase I
16. Metaphase I
16. Anaphase II
17. Interphase
• Interphase (technically not part of meiosis, you’re right!)
17. Telophase II and Cytokinesis
18. The diagram shows Crossing over
19. It occurs duringProphase I of meiosis
20. The result is a newcombination of alleles/genes(Differing chromosomes)
MITOSIS MEIOSISFORM OF REPRODUCTION
ASEXUAL SEXUAL (FIRST STAGE)
NUMBER OF DAUGHTER CELLS

CHANGE IN CHROMOSOME NUMBER
NO CHANGE (STAYS DIPLOID)
HALVED OR CUT IN HALF (HAPLOID)
NUMBER OF CELL DIVISIONS
1 2
DIFFERENCES IN ALLELES BETWEEN PARENT AND DAUGHTER CELLS
DOESN’T CHANGE GENETICALLY DIFFERENT FROM
PARENT
22.
• A diploid cell that enters mitosis with 16 chromosomes will divide to produce __2__ daughter cells. Each of these daughter cells will have __16__ chromosomes.
• *Remember, mitosis doesn’t change the daughter cells – they’re identical to parent
23.
• If the diploid number of chromosomes for an organism is 16, each daughter cell after mitosis will contain __16__ chromosomes.
24.
• A diploid cell that enters meiosis with 16 chromosomes will pass through __2__ cell divisions, producing __4__ daughter cells, each with __8__ chromosomes.
• Diploid cell haploid cell• Double - half
25.
• Gametes have a haploid number of chromosomes.
• Half as many as a normal body cell• Ex: Humans have 46 chromosomes, except in
gametes (sperm/egg) which have 23 (haploid)
26.
• If an organism’s haploid number is 5, its diploid number is 10.
• If given the haploid, double it• If given the diploid, halve it
27.
• While a haploid number of chromosomes may be even or odd, a diploid number is always even.
