Summary Introduction
Introduction:
A gene is the basic functional unit for heredity. Genes are composed of the DNA strands and are located on the chromosomes. Genes are instructions to make the protein by the process of transcription and translation. The location where the gene is placed in the chromosome is termed as the locus of that gene.

- Which of the following defines a genotype? The particular set of alleles that is carried in an individual’s chromosomes A part of a chromosome that encodes an RNA or protein product in its DNA sequence Forms of a gene with slightly different DNA sequences that may encode slightly different versions of the gene’s product An individual’s observable traitsarrow_forwardThe IA allele is to the IB allele and to the i allele. codominant; codominant codominant; completely dominant completely dominant; codominant completely dominant; completely dominantarrow_forwardA gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a husband and wife, who are both carriers of the sickle-cell anemia allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele being equally likely. Complete parts a) through c) below. a) Genes are always written with the dominant gene first. Therefore, there are two instances the offspring could have genotype Ss (one if the mother contributes the dominant allele and the father contributes the non-dominant allele; and one if the father contributes the dominant allele and the mother contributes the non-dominant allele). List the other two possible genotypes of the offspring. (Use a comma to separate answers as needed.)arrow_forward

- In man, muscular dystrophy is a condition in which the muscles waste away during early life and may result in a shorter life expectancy. It is due to a sex-linked, recessive gene. A certain couple has five children – three boys (ages 1yr, 3yrs, and 10yrs old) and two girls (ages 5yrs and 7yrs old). The oldest boy shows the symptoms of this disease. You are their family physician and they come to you for advice. What would you tell them about the chances of their other children developing the disease?arrow_forwardWhich of these terms is correctly matched with its definition?a. autosome—an X or a Y chromosomeb. phenotype—the genetic makeup of an individualc. allele—variant form of a gene occupying locus on a homologouschromosomed. heterozygous—having two identical genes for a traite. recessive—a trait expressed when the genes are heterozygousarrow_forwardIs Punnett square is used to predict possible genetic outcomesarrow_forward
