Answer 2

1. No natural selection
2. No mutations
3. No migration
4. Random mating
5. Infinitely large pop. size

Question 3

genetics

Translocation

Answer 3

Translocation means a change in location. It often refers to genetics, when part of a chromosome is transferred to another chromosome.

Question 4

genetics

Aneuploidy

Answer 4

Cell is missing 1 chromosome, or has 1 chromosome too many. N does not equal 46.

Question 5

genetics

Polyploidy

Answer 5

Refers to having 3+ whole sets of chromosomes. Rare in humans.

Question 6

genetics

Trisomy

Answer 6

Aneuploidy where there is an extra chromo.

Question 7

genetics

Monosomy

Answer 7

Aneuploidy where there is one missing chromo.

Question 8

genetics

Duplication

Answer 8

A type of mutation in which one or more copies of a DNA segment is produced.

Question 9

genetics

Nondisjunction

Answer 9

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division.

Question 10

plants

Xylem vs Phloem.

Answer 10

Xylem distributes H2O and MINERALS from bottom up(one-way), phloem distributes CO2 and food from leaf down (two-way)
