|
chromatid
|
one of two identical "sister" parts of a duplicated chromosomes
|
|
|
cell cycle
|
series of events in which a cell grows, prepares for division, and divides to form two daughter cells
|
|
|
interphase
|
period of the cell cycle between cell divisions
|
|
|
prophase
|
first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
|
|
|
chromatin
|
substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
|
|
|
centriole
|
structure in an animal cell that helps to organize cell division
|
|
|
metaphase
|
phase of mitosis in which the chromosomes line up across the center of the cell
|
|
|
anaphase
|
phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
|
|
|
telophase
|
phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
|
|
|
genetics
|
scientific study of heredity
|
|
|
fertilization
|
process in sexual reproduction in which male and female reproductive cells join to form a new cell
|
|
|
allele
|
one of a number of different forms of a gene
|
|
|
principle of dominance
|
Mendel's second conclusion which states that some alleles are dominant and others are recessive
|
|
|
segregation
|
separation of alleles during gamete formation
|
|
|
independent assortment
|
one of Mendel's principles that states that genes for different traits can segregate independently during the formation of gametes
|
|
|
incomplete dominance
|
situation in which one allele is not completely dominant over another allele
|
|
|
codominance
|
situation in which the phenotypes produced by both alleles are completely expressed
|
|
|
polygenic trait
|
trait controlled by two or more genes
|
|
|
diploid
|
term used to refer to a cell that contains two sets of homologous chromosomes
|
|
|
haploid
|
term used to refer to a cell that contains only a single set of genes
