Module 01 Lab Worksheet: General Review Introduction This week’s lab will focus on reviewing the concepts of anatomical terminology‚ metric conversion and genetics‚ specifically the concept of dominant and recessive alleles in a human pedigree. Objectives Objectives for this week’s lab include: 1) Review anatomical terminology‚ 2) Demonstrate metric conversion knowledge‚ and 3) Review the concepts of genetic inheritance and demonstrate knowledge of the inheritance patterns of dominant and recessive

rules of probability apply to genetics. T 2. If an individual has a Gg genotype‚ half of his gametes should have the G allele‚ and the other half should have the g allele. F 3. A Punnett square is a chart that allows you to easily determine the expected genotypes in the offspring of two parents. (expected percents) T 4. In a cross between two homozygous dominant individuals‚ 25% of the offspring may have the recessive phenotype. F 5. A parent cell makes gametes through the process of mitosis. T 6

i. Allele ii. Genotype b. Dominant alleles are represented by: i. an upper case letter ii. a lower case letter iii. it does not matter what type of letter is used c. In fruit flies‚ gray body color is dominant over black body color. Using the letter G to represent body color‚ what is the genotype of a heterozygous gray bodied fly? i. GG ii. gg iii. Gg iv. GGgg d. All of the offspring of two gray bodied flys are also gray. What can you conclude about the genotypes of the parent flies

markers and phenotypes of weedy rice plants (seed awn and pericarp colour).Besides‚ this practical was aimed to understand chi-square analysis to test the genetic association. Understanding the concept of linkage disequilibrium was also one of the objectives of this practical. Chi-square statistical analysis was used to identify the association between markers and phenotypes of weedy rice plants tested. Results: For Awn and Awnless: Table 1.0: Chi-square calculation of phenotype I (awn-awnless)

Anthocyanin in Brassica rapa Abstract The foundation of genetics lies with the principles that Gregor Mendel outlined after his experiments with pea plants where he discovered the relationship between physical characteristics‚ or phenotype‚ and genetic traits‚ or genotype. This experiment aimed to reproduce Mendel’s results with the Brassica rapa plant‚ noted for it’s fast generation time‚ and anthocyanin‚ a purple pigment that can be visually tracked through subsequent generations. It is important
