Science Vocab Test
This is a StudyStack for the Genetics Vocab Test
Term | Definition |
---|---|
heredity | the passing of trait from parent to offspring |
allel | alternate form that a gene may have, can be dominant or recessive |
genetic | the study of how traits are inherited through the action of alleles |
hybrid | an offspring that was given different information for a trait from each parent |
dominant | describes a trait that covers over, or dominates by another form of that trait |
recessive | describes a trait that is covered over or dominated by another form of that trait and stem to disappear |
punnet square | a tool to predict the probability of certain traits in offspring that shows the different way alleles can combine |
genotype | genetic makeup of an organism |
phenotype | outward physical appearance and behavior of an organism as a result of its genotype |
homozygous | describes an organism with two alleles that are the same for a trait |
herterzygous | describes an organism with two different alleles for a trait |
incomplete dominance | production of a phenotype that is intermingled between two homologous parents |
poly genetic inheritance | occurs when a group pairs acts together and produces a specific trait, such as human eye color, skin color, and height |
sex-linked gene | an allele inherited on a sex chromosome and that can cause human genetic disorders such as blindness or hemophilia |
genetic engineering | biological and chemical methods to change the arrangements of gene DNA to improve crop production, produce large volumes of medicine, and changes how cells preform their normal functions. |
