Heterozygous - When two different alleles combine to form a trait. Example: A tall person and a short person have a child who is short. The short allele is dominant so the child grew up to be short. Gene - A section of DNA that controls a certain trait. Example: Eye color. Dominant - Determines the expression of a trait (visually). Example: Brown eyes, dark hair. Homozygous - A homozygous trait is when two of the same kind of alleles combine to form a trait. Example: When two tall...

An error in mRNA transcription of a gene (substitution of a base) will be less detrimental than that same base substitution in the DNA of the gene (T or F). correct answersTrue Mitosis is the process that cells use for growth and replacement and meiosis is the process cells use for creating gametes (T or F). correct answersTrue The genotype of an individual depends on the phenotype of the individual (T or F).
