Directions: Fill in each blank with the word that best completes the reading comprehension.

Scientists who study genetics study genes and heredity: how certain characteristics are inherited by offspring because their parents had these characteristics. Do you have the same eye color as your mother or father? Do twins "run" in your family? These characteristics, or traits, are inherited. They are passed from your parents to you by genes. Genes (1) ____contain________ DNA that occupies a (2) _________specific_________ place on a chromosome. DNA (3) ___________Determines____________ a specific trait in the (4) ____________organism___________ . Even the fact that you were born a boy or a girl was determined by genes. DNA is found in the (5) __________nucleus_____________ of each cell. When a baby is made, one cell from the father joins with one cell from the mother. This tiny cell (6) __________contains_____________ all the information stored in DNA to make a new person - you! If you are a boy, you were given DNA from your father containing a "y" chromosome. If you are a girl, you were given DNA from your father (7) _________containing______________ an "x" chromosome. Your mother could only give you an x chromosome. Girls have two x chromosomes, and boys have an x and a y chromosome. The information in the DNA you inherited from your parents also (8) __________determine____________ what color of eyes you would have, the color of your hair, the type of ear lobes you have, and whether or not you can roll your tongue. The first geneticist was Gregor Mendel. In 1865 he published a paper describing experiments he did with garden peas. He noticed that certain traits in the parent

    The founder of genetics, Gregor Mendel, showed that parents passed genes to offspring. Genes code for traits. For example, Mendel demonstrated that a single gene codes for the color green in peas. A single gene also codes for the color yellow in peas. The geneticists who followed Mendel had no difficulty extrapolating his findings to the rest of life. Of particular interest was the role of heredity in humans. In a casual way, people had long appreciated the importance of heredity, noting for example that a child looked strikingly like his or her mother. Geneticists sought to formalize observations of this kind, tracing, for example, the transmission of the gene for brown eyes through several generations of a family. In the course of this work it was natural for geneticists to wonder whether intelligence and traits of character were inherited with the lawlike regularity that Mendel had observed with simple traits in…

    DNA consists of two polynucleotide chains and these nucleotides consist of a deoxyribose sugar, a nitrogenous base and a phosphate group. The bases are Adenine, Cytosine, Guanine and Thymine. The sequence of these bases on DNA determines the structure of these proteins. A gene is a sequence of bases which codes for a single polypeptide. Chromosomes carry these genes and these genes come in specific forms called an allele which is how living organisms vary from each other. For example, humans are made up of an XY or XX chromosome. Females are XX and males are XY, however in some animals their sex is determined by the ZW sex-determination…

    Eugenics, meaning “well born” is a term coined and a field created by Francis Galton, a British scientist. In 1869, Galton constructed pedigrees of leading English families using biographical information from obituaries and other sources and concluded that superior intelligence and abilities were inherited with an efficiency of 20%. From this research Galton theorized that if the fittest members of society were to have more children then humanity could be improved. In the early 1900s the eugenics movement gained much attention in the United States and lead to the rediscovery of Mendel’s experiment conducted in 1865, which explored the inheritance patterns of certain characteristics in pea plants. Since scientist, specifically animal breeders have been using disassortative mating for centuries in order to successfully improve their livestock; eugenics researchers believed they could carefully control human mating. Eugenics researchers believed that if mating could be controlled conditions like mental retardation and physical disabilities could be…

    Our bodies are made up of cells and within those cells hold our unique DNA and genetic make-up called genes. Genes are made up of strings of DNA and contain the directions that our bodies use to make the millions of proteins our bodies use (Ireland, 2010). Our genes are further organized into something called a chromosome. A chromosome contains our genes and in those genes you will find our DNA (Ireland, 2010), so you can say that our bodies are like a huge filing cabinet and the chromosomes are the folders where our information is stored. Chromosomes come in pairs and the human body has 23 pairs of chromosomes making up 46 individual units of organized DNA (Ireland, 2010). Each chromosome pair has one chromosome from the egg and one from the sperm, so genetic factors are important in establishing our individuality and the possibility of inheriting disease from one or both of our parents.…

    Genetics, which is the science of heredity, has four major areas. One of these areas is called transmission or Mendelian genetics, which deals with the transmission of genes from generation to generation (Russell 2003). Within this area, there are hereditary traits, which are controlled by genes. As studied by Mendel, genotype and phenotype are both characteristics of an organism. Genotype is the genetic make-up of an organism while phenotype is the observable characteristics of an organism. The expression of a trait, phenotype, can be affected by the…

    Charles Darwin, a famous naturalist and geologist, who developed the theory of evolution and natural selection. Darwin concluded his work with observations of birds, but didn’t have strong evidence to prove his theory. As of a couple years ago, a group of scientist from the University of Utah did an experiment on DNA from pigeons. From the experiment, the scientists were able to conclude that Darwin’s theory was correct (Osborne). Genetic research is well known as the practice of analyzing DNA strains as well as modifying DNA strains. DNA is like a thousand page book about yourself. Genetic research has opened up doors to many new experiments and questions. Genetic research has been a huge controversy throughout the whole world. Genetic research is viewed as either as destroying or improving the lives of people. Genetic research has helped create solutions for many diseases, solve investigations easier, as well as, being able to find family member. So without a doubt genetic research has improved our lives.…
