## Step 1<br />The first question is asking for the term that describes the study of genes and how traits are passed down from one generation to the next. The correct answer is "Genetics", which is the branch of biology that studies heredity and variation in organisms.<br /><br />## Step 2<br />The second question is asking for the term that describes the process of passing traits from parents to offspring. The correct answer is "Heredity", which is the passing on of physical or mental characteristics genetically from one parent or set of parents to their children.<br /><br />## Step 3<br />The third question is asking for the term that describes the nucleic acid that contains the genetic information for heredity in most organisms. The correct answer is "DNA", which stands for Deoxyribonucleic Acid. It is the molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.<br /><br />## Step 4<br />The fourth question is asking for the term that describes segments of DNA that contain codes for the production of proteins. The correct answer is "Genes", which are the basic physical and functional unit of heredity made up of DNA.<br /><br />## Step 5<br />The fifth question is asking for the term that describes thread-like structures containing tightly coiled DNA found inside the nucleus of a cell. The correct answer is "Chromosomes", which are thread-like structures located inside the nucleus of animal and plant cells.<br /><br />## Step 6<br />The sixth question is asking for the term that describes an allele that is expressed in the phenotype when at least one copy is present. The correct answer is "Dominant", which refers to the allele that is expressed in the phenotype when at least one copy is present.<br /><br />## Step 7<br />The seventeenth question is asking for the term that refers to two identical alleles. The correct answer is "Homozygous", which refers to an individual with two identical alleles for a particular trait.<br /><br />## Step 8<br />The eighteenth question is asking for the term that describes an organism's observable characteristics or traits. The correct answer is "Phenotype", which is the set of observable characteristics or traits of an organism.<br /><br />## Step 9<br />The nineteenth question is asking for the term that describes the genetic makeup of an organism, represented by pairs of letters such as BB, Ss, or aa. The correct answer is "Genotype", which is the genetic makeup of an organism.
