Answer: if both homologous chromosomes carry the same allele at a given gene locus (also called true-breeding) Q: what makes a specific locus heterozygous?

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...

Penn Foster - Biology Lesson 3, Genetics and Inheritance, Exercise & Self-Check Answer Key with Complete Solutions What is a genotype? The genetic constitution of an individual, represented by the combination of alleles. What is a phenotype? The observable physical or biochemical characteristics of an organism determined by the genotype and environment. What is the principle of segregation in genetics?

what are two factors that contribute to phenotype? Correct Answer-genotype and environment species Correct Answer-individuals that are able to exchange genetic material gene pool Correct Answer-all alleles present in individuals of that species populations Correct Answer-interbreeding groups of organisms of the same species living in the same geographical area what are two main sources that lead to genetic variation? Correct Answer-mutation and recombination what can somatic mutat...

Introduction: An organism’s traits, or characteristics, are controlled by genes. Genes are located on rod-like structures called chromosomes. Different versions of genes that code for the same trait are called alleles. In this Gizmo, there are 3 genes on each chromosome. For each gene there are eight possible alleles: W (white), R (red), G (green), B (blue), C (cyan), M (magenta), Y (yellow), and K (black). Question: Where does variation in a population come from? 1. Observe: Click on on...

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...
