Question | Answer |
---|---|
the process of intentionally interfering with the breeding process to encourage certain traits over others | artificial selection |
the structure in the cell nucleus that houses a cell's genetic information | chromosomes |
these are organisms that come from the same cell and are genetically identical to each other | clones |
a type of heredity where two dominant alleles are equally expressed in phenotype | codominance |
the inability to perceive differences between some or all hues that other people can distinguish, most of the time it is due to genetics | colorblindness |
the process in which chromosomes exchange DNA during the prophase of meiosis | crossing over |
an autosomal recessive diserase that affects the respiratory & digestive systems, mucus in lungs | cystic fibrosis |
a genetic mutation caused by the loss of a chromosomal segment | deletion |
the inheritance of alleles of two genes from two different parents | di-hybrid cross |
a technique used to distinguish between individuals using samples of DNA | DNA fingerprinting |
an observable trait or an organism that can mask the recessive trait | dominant |
the process of seperating DNA fragmanets by using an electric field & a fluorescent dye | electrophoresis |
a genetic mutation caused by the insertion or deletion of one or more nucleotides that change the amino acid sequence from the site of the mutation foreward | frameshift |
a segment of DNA on the chromosome that is coded for a particular trait | gene |
this is the insertion of genes into an individuals tissues to treat a disease, hereditary diseases in particular | gene thera[py |
these are inherited diseases that cause a negative, abnormal physical effect | genetic disorder |
one result of gamete formation through meiosis and fertilization during sexual reproduction that promotes biodiversity within a species | genetic variation |
the genetic makeup of an organism | genotype |
a genetic disorder that impairs bloods ability to clot | hemophilia |
the transfer of characteristics from parent to offspring | heredity |
this is an organism that has two different alleles for a trait | heterozygous |
two same alleles | homozygous |
mapped all genes in human genome | human genome profect |
offspring between parents with different traits | hybrid |
alternative form of a gene | allele |
a person who shows no symptoms of a disease but carriees the disease causing agent & is capable of passing it to others | carrier |
an organism or cell with two sets of chromosomes | diploid |
process of manipulation the DNA code of different dpliving organsims | genetic engineering |
a cell or organism having 1/2 of the diploid chromosome number, symbolized by "N' | haploid |
a chart or family tree that tracks which memebers of a family have a particular trait | pedigree |
the process of selecting organisms with desired traits to be parents of the next generation | selective breeding |
a picture of all the human chromosomes in a cell grouped together in pairs and arranged in order of decreasing size | karyotype |
a selective breeding method in which 2 individuals with similar set of alleles are crossed | inbreeding |
a selective breeding method that involves crossing different individuals to bring together the best traits from each parents | hybridization |
a complete set of genetic information that an organism carries in its DNA | genome |
