Dihybrid cross - Study guides, Class notes & Summaries

Epistasis refers to - The expression of one gene masking the expression of another. Which statement about a dihybrid cross is true? - It is a cross between identical double heterozygotes Which statement about mitosis is true? - Two genetically identical daughter cells are formed. Separation of the alleles of a single gene into different gametes is called - Segregation A mechanism for increasing the genetic diversity of offspring is - Sexual reproduction. In mitotic metaphase, a cell with e...

BIO 182 Exam 2 Questions with Correct Answers In a simple Mendelian monohybrid cross, true-breeding tall plants are crossed with short plants, and the F1 plants, which are all tall, are allowed to self-pollinate. What fraction of the F2 generation are both tall and heterozygous? a. 1⁄8 b. 1⁄4 c. 1⁄3 d. 2⁄3 e. 1⁄2 - Answer-e. 1⁄2 The phenotype of an individual a. depends at least in part on the genotype. b. is either homozygous or heterozygous. c. determines the genotyp...

1. Three (3) eggs are boiled and all weigh 2g. The eggs are placed in a 15% solution ofNaCI and reweighed after 30 minutes. Tell me which egg was isotonic to the NaClsolution, which egg was hypotonic to the NaCI solution, and which egg was hypertonic tothe NaCl solution and explain how you know this. - Egg 1 = 2.5 grams hypertonic, Egg 2 = 2 grams isotonic, Egg 3 = 1.8 grams hypotonic. 5 properties of life - cellular organization, metabolism, homeostasis, growth and reproduction, heredity ...

Explain how Mendel cross pollinated his pea plants - Hand pollinated Explain the difference between dominant & recessive alleles - Dominant is stronger and will show up with a better chance than recessive Give 4 reason that Mendel used garden peas for his experiments - Small area, lots of offspring, self pollinate, and artificially cross pollinated Heterozygous genotypes are also called - Hybrid How did mendel get pure plants - He allowed the plants to self-pollinate for several generation...
