MEIOSIS 
Prophase I – 4DNA, 2n 
- Homologous chromosomes here have already been replicated 
- Homologous chromosomes line up along their lengths and are connected by 
synaptonemal complex (protein complex) 
o Synapsis 
- Homologous chromosomes = a duplicated pair from mom similar in length and gene 
position to a duplicated pair from dad 
o They pair up during meiosis I
Summary
Bio 311D Unit 1 Test Review
PopularThis study guide covers the four modules of Dr. Engler's 311D Bio Unit 1. The first module includes diagrams over mitosis and meiosis, compares and contrasts sexual and asexual reproduction, and covers the origin of genetic variation. The second one goes over Mendel's laws and their exceptions. Module 3 covers evolution, including Hardy weinberg problems and evolutionary forces that alter allele frequencies. Finally, the fourth covers natural selection, reproductive barriers, speciation, a...

QUESTIONS 
 
1.	Compare and contrast mitosis and meiosis in terms of cell activities and chromosome number in daughter cells. 
 
a.	Mitosis: 2n, two daughter cells 
 
b.	Meiosis: n, four daughter cells 
 
2.	Describe how genetic variation among individuals is generated by meiotic independent assortment and recombination. Be able to label and follow alleles on chromosomes. 
a.	Independent assortment: each pair of alleles separate from each other during gamete formation ...

Speciation: 
1. Biological Series Concept - a group of populations whose members have the potential to 
interbreed in nature and produce viable, fertile offspring, but do not produce viable, fertile 
offspring with members of other such groups → reproductive isolation 
2. Speciation - species arise when individuals in a population become isolated from one another 
2.1. Genetic drift 
2.2. Natural selection 
2.3. Recombination
