MS-LS3-1
State Required Vocabulary for Standard MS LS3-1
| Question | Answer |
|---|---|
| Genome (MS-LS3-1) | The complete set of genetic material in an organism, including all of its DNA, which contains the information needed to build and maintain the organism. |
| Genotype (MS-LS3-1) | The genetic makeup of an organism, specifically the combination of alleles it inherits from its parents for a particular trait. |
| Phenotype (MS-LS3-1) | The observable characteristics or traits of an organism, such as physical appearance, behavior, and biochemical properties, which result from the interaction of its genotype with the environment. |
| DNA (Deoxyribonucleic Acid) (MS-LS3-1) | The molecule that carries genetic information in all living organisms. DNA is composed of two strands that coil to form a double helix, with sequences of four nucleotides (A, T, C, G) coding for genes. |
| Pedigree (MS-LS3-1) | A diagram that shows the occurrence and inheritance of a trait within a family across multiple generations, often used to study genetic disorders. |
| Parent generation (MS-LS3-1) | The first generation in a breeding experiment (often labeled as the "P" generation) from which offspring are produced. |
| Trait (MS-LS3-1) | A specific characteristic of an organism, such as eye color, height, or leaf shape, that can be inherited genetically. |
| Positive (MS-LS3-1) | In genetics, a positive trait or effect that is beneficial or advantageous for the organism's survival, health, or reproduction. |
| Negative (MS-LS3-1) | A trait or effect that may be harmful or reduce the organism’s ability to survive, thrive, or reproduce. |
| Neutral (MS-LS3-1) | A trait or genetic change that has no significant effect on the organism’s fitness or survival. |
| Pollination (MS-LS3-1) | The process by which pollen is transferred from the male part (anther) to the female part (stigma) of a plant, leading to fertilization and the production of seeds. |
| Punnett square (MS-LS3-1) | A chart used in genetics to predict the possible genotypes of offspring from a cross between two parents, based on their genotypes for specific traits. |
| Dominant trait (MS-LS3-1) | A trait that is expressed in the phenotype even if only one copy of the allele responsible for it is present. It "dominates" over a recessive trait. |
| Recessive trait (MS-LS3-1) | A trait that is only expressed in the phenotype when two copies of the allele responsible for it are present (when the dominant allele is not present). |
| Allele (MS-LS3-1) | A variant form of a gene. Organisms inherit two alleles for each gene, one from each parent, which may be the same or different (dominant or recessive). |
