Question 1 • The man considered the father of modern genetics, who also determined how genes are inherited is: Charles Darwin Louis Pasteur Isaac Newton Gregor Mendel

Question 1 Correct! • Gregor Mendel, an Augustinian monk, is considered the father of modern genetics. Mendel’s work with pea plants resulted in a basic understanding of how traits are passed on from generation to generation. Since the principles of heredity are similar for all higher life forms, Mendel’s work with pea plants was relevant to many other species as well. Go to question 2

Question 1 Incorrect • Sorry, try again

Question 2 • In higher organisms the genetic material, or DNA, is usually located within what part of the cell? Cytoplasm Ribosome Endoplasmic reticulum Nucleus

Question 3 • The basis of all hereditary material is DNA. DNA is made from: a nitrogen containing base a phosphate molecule a sugar molecule all the above

Question 3 Correct! • DNA consists of double helix or twisted ladder formation held together at the rungs by nitrogen-containing bases. The sides of the ladder consist of sugars and phosphates. One unit of a nitrogenous base, sugar and phosphate is referred to as a nucleotide. • Go to question 4

Question 2 Correct! • The hereditary material of a cell, DNA, is located within the nucleus of the cell unless the cell is undergoing cell division. Simple life forms, such as bacteria, do not have a specialized structure that contains the DNA. • Go to question 3

Question 4 • This type of gene completely expresses its effect or outcome on an organism regardless of the makeup of the other gene within a gene pair. recessive gene dominant gene or allele autosome

Question 4 Correct! • A dominant gene or allele will express itself regardless of what the other gene of the pair may be. For example, if T is completely dominant for tallness, then a plant will be tall with each of the following gene pairs: TT or Tt. Go on to question 5

Question 5 • The physical traits or appearance of an organism is determined by the genetic material inherited from their parents. The word used to describe one's inherited appearance is: Phenotype Genotype Homozygote Heterozygote

Question 5 Correct! • Phenotype is the traits and observable physical appearance an organism acquires as a result of the specific genes it inherits. If T is completely dominant for tallness, then we could say that a plant with a T gene has a phenotype or appearance of tall. Go on to question 6

Question 6 • The combination of genes that an organism inherits from its biological parents are unique to each individual. The actual genes an organism possesses is referred to as its: Gene pool Phenotype Genotype Genetic code

Question 6 Correct! • An organism's genotype is the set of genes possessed in a gene pair or within the entire organism. If a plant had inherited the genes T t for height we would say that its genotype consists of the genes "Tt." Genotype does not take into account the appearance of an organism. Go on to question 7

Question 7 • For years humans have experimented with the mating of different strains of plants and animals to produce superior offspring. When two genetically different strains of organisms mate, the offspring that result are referred to as: Purebreds Hybrids Homozygotes Mutants

Question 7 Correct! • When two genetically different parents mate, the offspring that result are called hybrids. The intent of hybridization is to produce offspring that contain the best qualities of both parents, a condition referred to as hybrid vigor. Hybridization may result in benefits such as higher yielding agricultural products. • Go to question 8

Question 8 • One of the most important characteristics of DNA and genes is that they can be passed on from generation to generation. The process that allows DNA to copy itself so it can be passed on to future generations is called: Replication Duplication Deletion Mutation

Question 8 Correct! • The process of DNA replication is what allows DNA to be passed on from one generation to the next. As a result, each of your biological parents contributed a roughly equal amount of DNA to you. • Go to question 9

Question 9 • Confusion often exists concerning the difference between a gene and a chromosome. A gene: Is a segment of DNA that codes for a specific trait or protein Is located on a chromosome Occurs in pairs All the above are correct

Question 9 Correct! • A gene is segment of DNA or a portion of a chromosome that codes for a specific trait or protein. Genes, which are located on chromosomes, occur in pairs with one gene of the pair coming from each biological parent. Numerous genes are usually located on one chromosome. • Go to question 10

Question 10 • It is often beneficial for scientists to consider the sum total of all of the genes that may exist within a reproducing population at any given moment. The aggregate of genes present in a population is referred to as the: Human genome Gene pool Genetic map Gene flow

Question 10 Correct! • The gene pool consists of the total collection of genes that exists within a population at any given time. This would include all the genes present within the reproductive members of the population from which sex cells could be derived. • Click here to end the quiz
