in 1902, the Boveri-Sutton Chromosome Theory unified the genetic laws of Mendelian inheritance with the physical structures of chromosomes observed in cells.

the oceanic dolphin Costero is officially the same species as the river dolphin Tucuxi, even though they have been unambiguously demonstrated to be genetically different.

the development of molecular biology was made possible due to the convergence between biochemistry and genetics.

despite a requirement for scientists to share data, over a quarter of geneticists could not access data required to validate research.

a Punnett square is a tool in genetics developed by British geneticist Reginald Punnett, and which biologists use to this day to predict the probability of possible genotypes of offspring.

microchromosomes are very tiny gene-rich chromosomes which are a typical genetic component in birds, and some groups of non-mammalian animals.

polydactyl cats, with extra toes as a genetic trait, were long considered good luck by many sailors, as the cats' extraordinary climbing and hunting skills were helpful in controlling shipboard rodents.

genopolitics studies the genetic basis of political behavior and attitude.

Exploring the Fundamentals of Genetics

1 For genes that are closer together, however, the lower probability of crossover means that the genes demonstrate ________ – alleles for the two genes tend to be inherited together.

2 It was discovered that the cell uses DNA as a template to create matching ________ (a molecule with nucleotides, very similar to DNA).

3 Error rates are usually very low—1 error in every 10–100 million bases—due to the 'proofreading' ability of ________.

4 The modern science of genetics traces its roots to ________, a German-Czech Augustinian monk and scientist who studied the nature of inheritance in plants.

5 However, the modern science of genetics, which seeks to understand the process of inheritance, only began with the work of ________ in the mid-nineteenth century.

6 DNA can also be amplified using a procedure called the ________ (PCR).

7 [68] When searching for an unknown gene that may be involved in a disease, researchers commonly use ________ and genetic pedigree charts to find the location on the genome associated with the disease.

8 Proteins can bind to other proteins and simple molecules, sometimes acting as enzymes by facilitating ________ within the bound molecules (without changing the structure of the protein itself).

9 By comparing the homology between different species genomes it is possible to calculate the evolutionary distance between them and when they may have diverged (called a ________).

10 An internal process of ________ occurs within the body and eventually mutations accumulate within cells to promote their own growth, creating a cancerous tumor that grows and invades various tissues of the body.
