independent assortment

Front

the phenomenon where homologous chromosomes align along the metaphase plate independently of one another

Back

turner syndrome

Front

a child is born with a single x chromosome, develops as a female, is small in stature, and is sterile

Back

metaphase I

Front

the phase in meiosis where independent assortment occurs

Back

telophase I

Front

the phase in meiosis where two new haploid nuclei are formed

Back

non sister chromatids

Front

crossing over occurs between these

Back

crossing over

Front

the exchange of genetic material between non sister chromatids of homologous chromosomes

Back

asexual reproduction

Front

a type of reproduction that is similar to cloning, all organisms have identical DNA

Back

testes

Front

meiosis occurs in this organ in males

Back

anaphase I

Front

the phase in meiosis where homologous chromosomes are pulled to opposite sides

Back

fertilization

Front

the joining of an egg and a sperm

Back

prophase II

Front

the phase in meiosis were the chromatin condenses into chromosomes

Back

metaphase II

Front

the phase in meiosis where the chromosomes line up in the center of the cell

Back

different

Front

in meiosis, the DNA in each of the gametes is __________________

Back

telophase II

Front

the phase in meiosis where two new nuclei are formed, resulting in four haploid cells

Back

down syndrome

Front

trisomy 21, a child is born with mental retardation and elfish features

Back

ovaries

Front

meiosis occurs in this organ in females

Back

cell plate

Front

a type of cytokinesis found in plant cells

Back

eggs

Front

the type of gamete found in females

Back

cleavage furrow

Front

a type of cytokinesis found in animal cells

Back

g1 phase

Front

the phase of interphase where the cell grows

Back

edward's syndrome

Front

trisomy 18, a child is born with severe defects, most die within the first year

Back

diploid

Front

two sets of chromosomes

Back

budding

Front

a type of asexual reproduction performed in yeast where a new identical organism buds off an anatomical point of the original organism

Back

nondisjunction

Front

occurs in anaphase 1, when a homologous chromosome fails to separate, or in anaphse 2, when a chromosome fails to separate

Back

prophase I

Front

the phase in meiosis where crossing over occurs

Back

metaphase I

Front

the phase in meiosis where homologous chromosomes line up in the middle of the cell

Back

chromatin

Front

during interphase, the DNA is found in this form

Back

s phase

Front

the phase of interphase where the DNA is duplicated

Back

parthenogenesis

Front

a type of asexual reproduction where an unfertilized egg develops into an identical female offspring

Back

cytokinesis

Front

the act of splitting newly formed cells

Back

g2 phase

Front

the phase of interphase where the cell continues to grow and correct errors in DNA replication

Back

zygote

Front

a fertilized egg, it is diploid

Back

sperm

Front

the type of gamete found in males

Back

haploid

Front

one set of chromosomes

Back

klinefelter's syndrome

Front

a child is born with xxy, develops as a male with subtle female characteristics such as wide hips and enlarged breasts

Back

sprouting

Front

a type of asexual reproduction where an identical offspring develops from a shoot of a root or a stump

Back

prophase I

Front

the phase in meiosis where the chromatin condenses into chromosomes and forms homologous pairs.

Back

anaphase II

Front

the phase in meiosis where the chromosomes are split into chromatids

Back

meiosis

Front

cell division process that occurs to produce gametes, results in four different haploid cells
