Review In groups of 2-4 AT YOUR TABLE

Draw/Show the chromosomes, in metaphase 1 of meiosis, for each parent Show the gametes from each parent RrTt RRTT RRTt RrTT RRTt RRtt RrTt Rrtt

Meiosis What IS crossing over? When does it happen? Tetrad? Independent assortment CHROMOSOMES sort independently

Meiosis WHY meiosis? What is the importance of sexual reproduction? Costs and benefits of crossing over?

Mapping 30 C-D B-D A-C B-C

Mapping 35 B-E B-C A-B A-D C-D 10 D-E 25

Meiosis Which genes/traits are most likely to be inherited together? Least likely? WHY?

Meiosis Gene mapping Difficult to map if there aren’t mutations

Meiosis vs Mitosis Compare and contrast Meiosis and mitosis SHOW AND EXPLAIN the similarities and differences Why undergo either?

Other Know the stages/phases of meiosis AND mitosis Notes from presentations Stem cells, differentiation, cancer, etc. Gene mapping link: R0hJ8A Or search “Bozeman Genetic Mapping” video
