What is genetics? Genetics is the study of inherited traits and their variation. What is Heredity? Heredity is the transmission of traits and biological information between generations, and genetics is the study of how traits are transmitted. What are genes? Genes are the units of heredity. Genes are biochemical instructions Read more…
allele Form of a gene. Each characteristic has two alleles. recessive trait that will only appear in the phenotype if organism inherits two of them; covered up by the dominant gene gamete sex cell; sperm or egg adenine A base thats found in DNA. It will only bond with Thymine. Read more…
hybrid An organism that has two different alleles for a trait. dominant An allele whose trait always shows up in the organism when it is present. gene The set of information that controls a trait; code in the DNA. alleles The different forms of a gene. heredity The passing of Read more…

DNA chemical that genes and chromosomes are made of genes controls the trait of an organism dominant trait the strong trait that is apparent in an organism punnett square chart showing the possible gene combination in a Read more…
Gene (genetics) a segment of DNA that is involved in producing a polypeptide chain Allele Alternative form of a gene Trait A characteristic that an organism can pass on to its offspring through its genes. Genotype An organism’s genetic makeup. Phenotype An organism’s physical appearance, or visible traits. Gamete Haploid Read more…
Genomics field of genetics that attempts to understand the content, organization, function, and evolution of genetic information contained in whole genomes. Structural genomics Studies the organization and sequence of genetic information contained within a gene Genetic Maps based on recombination frequencies Physical maps based on the direct DNA sequence (Map-based Read more…
Heredity Passing of traits from parents to offspring Genetics Branch of biology that studies heredity Monohybrid Cross A cross between individuals that involves one pair of contrasting traits True-Breeding All of the offspring display only one form of a particular trait P Generation First two individuals crossed in a breeding Read more…
Every living thing needs a set of instructions that are necessary to live and grow. Where are these instructions found? DNA What does DNA encode? protein DNA is an abbreviation for deoxyribonucleic acid The twisted ladder shape of DNA is called double helix We have 26 letters in our alphabet. Read more…
DNA Deoxyribonucleic acid; The genetic material that carries information about an organism and is passed from parent to offspring. Gene A segment of DNA found on a chromosome that determines the inheritance of a particular character Chromosome Thread like structures, made of DNA and contains many genes Alleles Different forms Read more…
genetics The scientific study of heredity Gregor Mendel Augustinian monk and botanist whose experiments in breeding garden peas led to his eventual recognition as founder of the science of genetics (1822-1884) trait specific physical characteristic that varies from one individual to another gene section of DNA that codes for a Read more…
Gene a heritable factor that controls a specific characteristic. Allele one specific form of a gene, differeing from other alleles by one or a few bases only and occupying the same locus as other alleles of the gene. Genome The whole of the genetic information of an organism gene mutation Read more…
Transmission genetics Deals with how genes and genetic traits are transmitted from generation to generation and how genes recombine Molecular genetics Deals with molecular structure and function of genes. Analysing the molecular events involved in the gene control of cell division or regulation of expression Population gwnetics Studies heredity in Read more…
alleles one of two or more different genes that code for similar proteins at the same locus on the chromosome. asexual reproduction no gametes are involved. It is just cellular division (mitosis); the offspring are identical to the parent. autosome any of the chromosomes other than the sex determining chromosomes Read more…
Gregor Mendel What is the name of the monk who developed the Genetic Theory? Genes Traits are passed from parents to offspring by what hereditary material? DNA What is the basic molecule that makes up genes? 4 How many different types of nucleotides or “building blocks” are found in the Read more…
Genetics The study of genes and their heredity Gene Segments of DNA that are information/ instructions for one trait Heredity The way genes are passed down (generations) Blending Theory of Inheritance The main theory of earlier genetics; states that an offspring is a mix of parents’ traits Gregor Mendel (1800s) Read more…
allele Any of the alternative forms of a gene that may occur at a given point on a chromosome. asexual reproduction Any type of reproduction that produces offspring without mating or fertilization. chromosome A DNA-containing structure that forms by the joining of two identical chromatids during cell division. clone An Read more…
What does heredity do to human life? Heredity affects many of our physical features as well as our susceptibility to many diseases and disorders. Genetics contributes to advances in agriculture, pharmaceuticals, and medicine and is fundamental to modern biology. All organisms use similar genetic systems, and genetic variation is the Read more…
Gregor Mendel Father of Genetics Trait The different forms of a physical characteristic (ex: height, eye color, hair color, petal color, stem height) Heredity The passing on of traits from parent(s) to offspring. Genetics The study of Heredity. Fertilization The joining of sperm and egg. Gene The factor that controls Read more…
Probability ________ is the measure of the likeliness that an event will occur.[1] ________ is quantified as a number between 0 and 1 (where 0 indicates impossibility and 1 indicates certainty).
