Learning from the Fossil Record Grade 8 Science Name: Date: Genes and Chromosomes Justified True or False Worksheet Statement Genes are found in DNA, which are found in chromosomes, which are found in a cell’s nucleus. True PRE JustificationWhy did you choose T or F? Traits can be found in your DNA because the DNA comes from your parents and that is where you inherit your traits from. I am just guessing!!! Each trait of an organism is determined by a gene. False I am just guessing!!! True Humans have 46 chromosomes, half come from each parent. False Not exactly half of your traits come from your mother and father. True The cells in a person’s eyes only have the eye color gene, all other cells do not have that gene. True Another part of the body would not have the color of your mother’s eye for example. False The other cells do have the eye color gene. Only some organism’s cells contain chromosomes, genes, and DNA. False I am just guessing!!! False EVERY organism’s cells contain chromosomes, genes, and DNA. We have two genes for each trait in our cells but each gene might have different instructions for the same trait. True I am just guessing!!! True The genes are the same type but they might contain different information and for example, one eye gene can hold the color blue while the other The instructions that determine an organism’s traits are found in an organism’s DNA. PRE True or False True POST True or False True POST JustificationWhy did you choose T or F? What controls the traits are called genes and these are found in your DNA. False Genes are found in chromosomes, which are found in DNA, which are found in the cell’s nucleus. You get 2 of the same types of genes (one from mother and 1 from father) but only 1 will be used. You get 23 from your mother and 23 from your father and this equals 46. Learning from the Fossil Record Grade 8 Science Name: Date: Genes contain information that can be passed from parent to offspring. True Genes can be passed down from your parents that contain information. True Inherited characteristics are called traits and are passed from parent to offspring. True You may have a trait that one of your parents might have. True Reproduction does not play a role in inheriting traits. False Without reproduction we could not inherit traits. False holds green but only one of these genes will be used. Genes hold information that can be passed to you and this affects the traits that you get. In reproduction the inherited characteristics are passed to you and these are called traits and could be similar from your mother or father. Without reproduction we could not inherit traits.
