Cb3 a,b, c and d

• Homozygous refers to having two identical alleles for a particular gene
• Heterozygous means having two different alleles for a particular gene
• Genotype refers to the genetic makeup of an organism
• Phenotype refers to the physical characteristics of an organism
• In Punnett squares, alleles are represented to predict the possible genotypes and phenotypes of offspring
• Punnett squares help determine the probability of traits being passed on from parents to offspring
• Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus
• Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell
• DNA bases are Adenine, Thymine, Cytosine, and Guanine
• DNA is made up of two strands that twist to form a double helix structure
• The DNA molecule consists of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base
• During cell division, DNA replicates to ensure each daughter cell receives a full set of genetic information
