Asexual Reproduction - ANS-Has genetic differences due to mutations

Sexual Reproduction - ANS-Found only in Eukaryotes

What is ploidy? - ANS-the # of chromosomes in a cell

What are 2 types of ploidy? - ANS-Haploid and Diploid

Define meiosis. - ANS-A form of nuclear division in which a diploid cell divides into 4
haploid cells

Define syngamy. - ANS-A process by which haploid gametes such as a haploid egg +
haploid sperm fuse into a diploid zygote

What are the 3 different types of genetic diversity? - ANS-- Mutation
- Genetic Recombination
- Syngamy

What does genetic recombination do in meiosis? - ANS-It crosses over to create 4
genetically distinct haploid nuclei

Syngamy is also known as: - ANS-The fertilization of 2 genetically distinct gametes

What does syngamy do? - ANS-It creates a new diploid individual that is genetically
distinct from either parent

How are meiosis and syngamy linked? - ANS-Meiosis produces gametes, and gametes
undergo syngamy.

What are some characteristics of a gametophyte? - ANS-- Haploid individual
- Haploid gametes
- By mitosis
- In gametangia

What are some characteristics of a sporophyte? - ANS-- Diploid individuals
- Haploid spores
- By meiosis
