PENN FOSTER BIOLOGY: Genetics and Inheritance Questions and Answers Already Passed What is the basic unit of heredity? The gene What is the principle of segregation in genetics? Each individual has two alleles for each gene, which separate during gamete formation so each gamete carries only one allele. What does a Punnett square illustrate? The possible genetic combinations resulting from a cross between two parents. What is the difference between homozygous and heterozygo...

Mendelian traits Correct Answer-A gene with two different alleles - simple dom. / recessive relationship Non-Mendelian Traits Correct Answer-Do not express ratios expected from mendelian inheritance Loss of function allele Correct Answer-type of lethal alleles, encode proteins necessary for survival gain of function allele Correct Answer-protein encoded by mutant gene changed so it gains new function wild-type allele Correct Answer-prevalent alleles in a population mutant allele ...

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...

Lab Report Format Expectations Utilize college level grammar and professional formatting when completing this worksheet. Pre-Lab Questions 1. In a species of mice, brown fur color is dominant to white fur color. When a brown mouse is crossed with a white mouse all of their offspring have brown fur. Why did none of the offspring have white fur? The offsprings did not have white fur because the bown fur is more domnant 2. Can a person’s genotype be determined by their phenotype? Why or wh...
