BIO 1500 chapter 10
1. behavior and interaction during meiosis explain inheri-
tance patterns seen in populations: Chromosome
2. Genes arranged in a order on chromosomes: linear
3. Who developed the chromosomal theory of inheritance? What does it state?
Who was the first to provide physical evidence supporting this theory?: - Walter
sutton and theodor boveri
- states that chromosomes carry the unit of heredity (genes)
- Eleanor Carothers
4. Chromosome sorting into pre-gametes is : random
5. Correlation between chromosome behavior during meiosis and Mendel's
abstract laws led to ...: Chromosomal Theory of Inheritance
6. Eleanor Carothers: first to provide physical evidence; observed independent
1/6
,chromosome assortment in grasshoppers
Then, after years of testing crosses with fruit fly, Drosophila melanogaster,
provided additional evidence that genes are on chro-
mosomes and that some genes are : Thomas Morgan, linked
7. Morgan discovered a mutation affecting fly eye color, inherited differently
by males and females; concluded that eye color gene is to X
chromosome
-> suggested random chromosome was the physical basis of
Mendel's model -> demonstrated that linked genes Mendel's pre-
dicted outcomes of independent assortment: linked, segregation, disrupt
8. Each chromosome can carry many linked genes: this explains how individuals
2/6
, can have many more traits than chromosomes (TRUE OR FALSE): TRUE
9. Morgan's lab suggested: alleles on same chromosome were not always inher-
ited together (linked) -> ...: During meiosis, linked genes somehow became unlinked (by crossing-over).
10. —point at which chromatids are in contact with each
other and may exchange segment -> suggested that alleles can
become : Chiasmata, Janssen, unlinked
