(Show your Punnett Square) 5. (5 points) In a dihybrid cross between RrTt and RRtt, what are the genotype and phenotype ratios of the offspring, assuming R and T are dominant? R codes for round seed, while r codes for wrinkled seed. T codes for tall height, while t codes for short height. (Show your Punnett Square).
24 linkage groups, 22 pairs of autosomes, and the X and the Y 13. Markers may be variable restriction sites, variable short repeated sequences, or single nucleotide polymorphisms (SNPs). 14. Linkage: inherited together as on the same chromosome. Marker: a gene or DNA sequence with a known location that can be used to localize a gene of interest with an unknown location.
PART ONE BLASTN 6a. Briefly explain what information is contained within this summary. This summary includes the identification and name of the species that the sequence originated from, the chromosome number, the accession value, and then the score and the e-value. 6b. Given your knowledge of sequence similarity measures, which color is least desirable?
Unit 8 Project 1. Would a person who could roll his/her tongue know their genotype for certain? Why? Since genotypes are the presents of genes on chromosomes, the only way to be certain of a person’s genotype is genetic testing. 2.
a. GgWw b. GGWW c. ggWW d. GGww e. ggww Check your work. Answer is e. If the genotype of an individual is to be tested, the best cross to perform is the testcross, to a homozygous recessive. All of the other crosses will allow potential recessive alleles in the yellow round
Each isolate has its own vertical lane (i.e., column). Controls appear in lanes #1, 5, and 10. Which isolates appear similar? In your opinion was DNA typing necessary in this case? Why?
Mendel’s Laws Explain each of Mendel’s Laws and explain the experiments he used to determine these laws. 1) Law of segregation of characters (alleles) When meiosis occurs, each of the pairs of alleles is separated and end up in different cells. Each gamete only receives one copy. 2) Law of independent assortment (of alleles) Each pair of alleles separate randomly. As long as alleles are on different chromosomes they will assort into the gametes independently of each other.
Radicals Tips 1. Make sure that one of the two factors of the radicand (expression under the radical) is the largest perfect square: Example: Simplify 72 Correct 72 = 36 ∙ 2 = 62 Incorrect 72 = 9 ∙ 8 = 38 2. To be able to add or subtract radicals, the radicands must be the same. Example 1: Add 32 + 52 Answer: Since radicands are the same, (3 + 5)2 = 82 Example 2: Subtract 73 - 3 Answer: (7 – 1)3 = 63 Example 3: 318 - 52 (Must simplify first) 39 2 - 52 3 ∙ 3 ∙ 2 - 52 92 - 520 Answer: 42

What value is stored in uninitialized variables? * Some languages assign a default value as 0 to uninitialized variables. Algorithm Workbench Review Questions: 3-10 3. Write assignment statements that perform the following operations with the variables a, b, and c. * Adds 2 to a and stores the result in b * Set b= 2 +a * Multiplies b times 4 and stores the result in a * set a= b*4 * Divides a by 3.14 and stores the result in b * set b= 3.14/b * Subtracts 8 from b and stored the result in a * set a= b-8 4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2.
