Q.
part of eukaryotic cell division during which the cell nucleus divides; creates 2 identical nuclei with diploid chromosomes (after interphase but before cytokinesis)
5
30 sec
Q.
series of events in which a cell grows, prepares for division, and divides to form two daughter cells (includes interphase, mitosis, and cytokinesis)
6
30 sec
Q.
division of the cytoplasm to form two separate daughter cells (last stage of the cell cycle after mitosis)
7

Q.
name for a Pair of chromosomes that are the same size, same appearance and same genes.
8
30 sec
Q.
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes
9
30 sec
Q.
specialized cell involved in sexual reproduction, sperm or egg
10

Q.
having a 'half-set' of unpaired chromosomes
11
30 sec
Q.
containing a complete sets of chromosomes, one from each parent completing homologues pairs
12
30 sec
Q.
"loose" DNA and proteins that is present during interphase
13
30 sec
Q.
Each half of the copied chromosome; attached at the center
14
30 sec
Q.
2 parents pass DNA from the sex cells on to their offspring. Half come from the male and half come from the female. offspring are all unique
15
30 sec
Q.
1 parent passes all of its DNA to offspring. Offspring is identical to parent
16
30 sec
Q.
A form of asexual reproduction in single-celled organisms where one cell divides into two cells of the same size
17
30 sec
Q.
Asexual reproduction in which a part of the parent organism "pinches off" and forms a new organism; yeast and hydra are examples
18
30 sec
Q.
single-celled reproductive bodies highly resistant to cold and heat damage; capable of new organisms as a type of asexual reproduction
19
30 sec
Q.
type of asexual reproduction found in some plants in which a piece of plant's root or stem is used to grow new plants
20

Q.
the differences in DNA between individuals of the same species - especially high in sexual reproduction
21

30 sec
Q.
A segment of DNA on a chromosome that codes for a specific trait

30 sec
Q.
An organism that has two identical alleles for a trait (both dominant or both recessive)
32
30 sec
Q.
An organism that has two different alleles for a trait (one dominant and one recessive)
33
30 sec
Q.
A pattern of inheritance in which one allele is completely dominant over another. the Phenotype is dominant only
34
30 sec
Q.
A pattern of inheritance in which two alleles are neither dominant nor recessive. The resulting phenotype is a blending of the parental traits.
35
30 sec
Q.
a pattern of inheritance in which both alleles of a gene contribute to the phenotype equally (but are not blended)
