Phases of Meiosis
Phase that occurs before Meiosos
What is Interphase
What are the two stages of Meiosis
MEIOSIS I and MEIOSIS II
What phases is this
What is telophase 1
The characteristics that can be observed (what it looks like)
What is phenotype
Round eyes are dominant to almond shape eyes. If a homozygous dominant woman mixed with a homozygous dominant male, what percent of their kids will have almond shape eyes?
What is 0 %
What 3 important events take place in Prophase 1
What is Chromatin condenses to form visible chromosomes, the nucleus and nucleolus disintegrate, homologous chromosome pair up to form tetrads
What is the correct order of phases for both Meiosis I and II?
What is Interphase, Prophase, Metaphase, Anaphase and Telophase
What phase is this
Metaphase 2
When the alleles in the genotype are the same; both are dominant or recessive (ex: HH or hh)
What is homozygous
Freckles are dominant to no freckles. If a homozygous dominant woman (BB) mixes with a heterozygous man (Bb), how many of their kids are going to have freckles?
What is 100%
Division of the cytoplasm occurs in what phase
What is Cytokinesis
Purpose of Meiosis
What is to make gametes
What phase is this
Prophase 2
A chart that shows all possible gene combinations in a cross of parents
What is a punnet square
Black hair is dominant to blond. If a heterozygous woman (Aa) mixes with a heterozygous male (Aa), what percent of their kids is going to have blond hair?
What is 25%
What takes places during Interphase
What is DNA replication, Protein Synthesis, and normal cell metabolism and activity
The end result of Meiosis produces how many cell
What is 4 haploid
What phase is this?
Anaphase 1
The actual genetic makeup of an organism
What is genotype
In Atlantis, breathing underwater is a dominant trait. Mrs. Maine (Zz) marries Mr. Maine (Zz), and they have kids. What percent of kids will be able to breath underwater?
What is 75%
What phase does crossing over occur?
What is Prophase
Pairing of homologous chromosomes prior to their separation into daughter cells
What is Synapsis
What phase is this
What is Metaphase
The trait expressed even if only one copy is present in the genotype (always written as a capital letter)
What is dominant
If a black heterozygous guinea pig is crossed with a homozygous white guinea pig with the genotype bb, what is the probability that the offspring will be white?
What is 50%
