Biology 102 Exam 2 WSU Carloye Latest Update 100% Solved 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 all...

Cellular Processes and the Genetic Environment 1. Describe cellular processes and alterations within cellular processes. Movement. Muscle cells can generate forces that produce motion. Muscles that are attached to bones produce limb movements, whereas those that enclose hollow tubes or cavities move or empty contents when they contract. For example, the contraction of smooth muscle cells surrounding blood vessels changes the diameter of the vessels; the contraction of muscles in walls of t...

Which gametes are responsible for sex? correct answer: The sex chromosomes (X or Y) Bipotential Primordium correct answer: Has both mullerian duct and wolffian duct, potential for either male or female development. XX Structure development correct answer: Mullerian duct persists and forms the fallopian tube, uterus, and upper third of the vagina, including the cervix. Wolffian duct regresses due to lack of testosterone. Gondal cortex forms ovary, gondal medulla regresses. XY extra ge...

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...

Gene vs Allele - Answer-Gene: A section of DNA that controls a certain trait. Example: Eye color. Allele: A specific variation of a gene. Example: Having blue eyes. Dominant vs Recessive - Answer-Dominant: Determines the expression of a trait (visually). Example: Brown eyes, dark hair. Recessive: Much less likely to determine the expression of a trait. Example: Blue eyes, blonde hair. Homozygous vs Heterozygous - Answer-Homozygous: A homozygous trait is when two of the same kind of allel...
