Question Answer
alleledifferent forms of the same gene
condominant both alleles of a gene are expressed in equal measure, example is red and white flower color when codominant, flowers might be striped red and white rather than solid red or solid white
crossa hypothetical or actual mating of two organisms
diploidindividual with a double set of chromosomes
dominant allele of a gene that is expressed most frequently; designated with a capital
fertilizationprocess of sperm and egg combining to form a zygote
gametesperm or egg; haploid
gene small segment of DNA on a chromosome that encodes a trait
genotypegene combination controlling the expression of a phenotype
genotype ratioratio of all possible combination of alleles in offspring
haploid having one set of chromosomes; many times a gamete
heterozygoushaving to different forms of the same gene
homologous chromosomes pair of chromosomes in a diploid individual; have the same size, structure and genetic make-up
homozygoushaving two of the same alleles
incomplete dominance combination of alleles that results in a blend of the two possible physical manifestations; example red vs white flowers- the intermediate or blend would be pink, neither red nor white
meiosis the process by which special gamete producing cells reduce their chromosome number by one half; reduction division
phenotype physical appearance of a trait dictated by the gene combination
Phenotype ratioratio of possible physical appearance of offspring
Pungent Squaretechnique used in the prediction of possible genetic combination resultant from fertilization
Recessiveallele of a gene that can be masked by the dominant allele; designated by the same letter as a dominant form only lower case
Zygotefertilized egg
Cytokinesisdivision of the cytoplasm
KaryokinesisDivision of nucleus has occurred
TelophaseDaughter chromosomes uncondensed
AnaphaseDyads separate, now we have daughter chromosomes
Metaphasedyads line up at the cell equator
Astersmicrotubules behind centrioles
Spindle fibersattach to chromosomes
Nucleusthe central and most important part of an object, movement, or group, forming the basis for its activity and growth.
Sister chromatidsalso called dyads, each chromosome has a copy
Chromatincondenses, see individual chromosomes
Centromerethe region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.
MitosisProcess by which we produce 2 identical cells to the parent cell; used for growth and injury repair
Interphaselongest phase, divided into 3 sub phases, G1- RNA and protein sythesus, S phase- DNA duplicated, G2 More RNA and protein synthesis
