Science Final

Allele(s) The different forms of genes.
Chromosomes any of several threadlike bodies, consisting of chromatin, that carry the genes in a linear order: the human species has 23 pairs, designated 1 to 22 in order of decreasing size and X and Y for the female and male sex chromosomes respectively.
Dominant trait The trait that is seen the most.
DNA deoxyribonucleic acid; a nucleic acid that is the main constituent of the chromosomes of all organisms (except some viruses).
Gene(s) Traits that you inherit from your parents.
Genotype the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
Heredity The transferring of genetics from parent to offspring.
Heterozygous When dominant and recessive traits are next to each other.
Homologous chromosomes Chromosomes that carry the same set of genes.
Homozygous Two dominant or two recessive trait next to each other.
Meiosis The process of cell division that only occurs in sex cells.
Mitosis The process of cell division that only occurs in body cells.
Mutation a sudden departure from the parent type in one or more heritable characteristics, caused by a change in a gene or a chromosome
Nucleotide any of a group of molecules that, when linked together, form the building blocks of DNA or RNA: composed of a phosphate group, the bases adenine, cytosine, guanine, and thymine, and a pentose sugar, in RNA the thymine base being replaced by uracil.
Pedigree A tool for tracing a tight through generations of a family.
Phenotype the observable constitution of an organism.
Recessive trait The trait that is seen the least
Ribosome Protein that is formed in a cell.
RNA ribonucleic acid: any of a class of single-stranded molecules
Sex chromosomes a chromosome, differing in shape or function from other chromosomes, that determines the sex of an individual.
Trait(s) a distinguishing characteristic or quality, especially of one's personal nature
Describe the significance if Mendel's work with pea plants He was the first to figure it out in the timeline he was in.
Describe the difference between Phenotype and Genotype and how a punnett square can help with probability of inheriting certain traits. Genotype is what you see on the outside and Phenotype is what you don't see.
