Term1/13
What is an allele
Definition1/13

a form of a gene apex

Term1/13
What is a tetrad
Definition1/13

Two sets of sister chromatids .

Term1/13
What must happen before meiosis can begin
Definition1/13

DNA doubles and produces sister chromatids before meiosis begins.

the chromosomes must replicate

Term1/13
What is the term for the two sets of chromatids formed in the parent cell
Definition1/13

Tetrad

Term1/13
What is true of the allele pair of someone with a genotype TT
Definition1/13

The allele pair of someone with a genotype TT is homozygous dominant.

Term1/13
Genetic disorders can result when chromatids fail to separate properly. During with phase is this problem most likely to occur
Definition1/13

Anaphase

Term1/13
A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells why would these be helpful in the treatment of tumors
Definition1/13

it would prevent tumor cells from reproducing.

Term1/13
What would happen if crossing over didn't happen during meiosis in humans
Definition1/13

If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.

Term1/13
How is the DNA in a prokaryote different from the DNA in a eukaryotes
Definition1/13

dna in eukaryotes is located in the nucleus

Term1/13
How are meiosis and mitosis different
Definition1/13

mitosis only has to do with celluar reproduction

meiosis has to do with sex cells reproducing
Mitosis creates new cells that are used for development, repair, asexual reproduction and growth. Meiosis creates cells in order for organisms to reproduce sexually.

Term1/13
What is the probability that a father produces a gamete with the allele for attached earlobes if he has one allele for detached earlobes and one allele for attached earlobes
Definition1/13

50%

Term1/13
The number of possible genetically different gamete for an organism quals 2n where n is the number of pairs of chromosomes if an organism has six pairs of chromosomes how man different gametes can it
Definition1/13

64 - Apex

Term1/13
Which best describes probability
Definition1/13

the likelihood that something will happen
