i. Mid-digit hair- Negative‚ recessive. j. Facial dimples- positive‚dominant. k. Freckles- Positive‚ dominant. l. Cleft chin- negative‚ resseive. 2. Can the student tell from the blood type if the student is heterozygous or homozygous? Explain. (5 points) Yes‚ knowing your blood type would enable you to determine it you are heterozygous or homeqygous. Examples of this would be BB is homozygous‚ and BO is heterozygous. If the student has an A bloodtype‚ AO would be herterozygous while AA homozygous

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica

Introduction The purpose of this experiment is to determine the maximum absorbance of fast green‚ and the chlorophylls‚ also in the case of fast green create a concentration curve to determine an unknown substance. Each test will use the spectrophotometer. Spectroscopy is the study of light. A spectrophotometer is a machine used to determine the absorbance of light at any given wavelength. It does this by using a source of white light through a prism‚ which gives multiple wavelengths that
