Heredity Study Guide


 * 1) Explain the relationship between traits and heredity.
 * 2) ===== What were the two main principles (rules or laws) that Mendel discovered from his experiments? (Hint: the answer is not about pollination or true-breeding plants. The answer is what allows use to interpret punnett squares). =====
 * 3) ===== What is the difference between gene and allele? =====
 * 4) ===== What is the difference between a dominant and a recessive allele? =====
 * 5) ===== What is the difference between genotype and phenotype? =====
 * 6) ===== What is the difference between heterozygous and homozygous? =====
 * 7) What is another word for heterzygous? Homozygous?
 * 8) ===== What are all the different ways to describe the genotype PP or pp? =====
 * 9) ===== What are all the different ways to describe the genotype Pp? =====
 * 10) ===== What is a punnett square? =====
 * 11) What do the letters on the outside of a punnett square represent? On the inside?
 * 12) ===== Be able to determine the phenotypic and genotypic probabilities by using a punnett square. =====
 * 13) Explain the differences between complete dominance and incomplete dominance?
 * 14) ===== If red flower had incomplete dominance over white flowers, and a red flower is crossed with a white flower, what color would the offspring be? =====
 * 15) ===== In rabbits, the allele for black fur, //B//, is dominant over the allele for white fur, //b//. Suppose two black parents produce four black offspring and one white offspring. What are the genotypes of the parents? =====
 * 16) ===== In rabbits, the allele for black fur, //B//, is dominant over the allele for white fur, //b//. Suppose two black parents produce five black offspring and two white offspring. What are the possible genotypes of all seven siblings? =====
 * 17) ===== Describe three exceptions to Mendel’s observations. =====
 * 18) ===== How is tossing a coin the same as a //Pp// parent giving a gene to an offspring? =====
 * 19) ===== Explain how genes and alleles are related to genotype and phenotype. =====
