Answer:
The use of the word "draw" here refers to the collection of blood samples for laboratory tests.
Step A - The first draw goes into the blood culture bottle or tube with a yellow cover.
Step B - This goes into the coagulation tube with a blue cover.
Step C - The next draw goes into the tube for non-additives. This usually has a red top
Step D - This features collection of blood into the tubes with additives. When dealing with additives, blood samples and additives it is important that the sample and additive is rigorously homogenized. This part can is broken down as follows:
- this goes into the SST tube. This tube contains a seperator and a clot activator and is usually is colour coded reddish-gray or gold top.
- This tube contains Sodium heparin and has a leaf green top
- This tube (PST) contains PST contains lithium heparin anticoagulant and a gel separator. It's cover is colour coded light green
- This tube contains Ethylenediaminetetraacetic acid or EDTA for short. It's cover is usually colour coded lavendar
- This tube is labelled ACD that is Acid Citrate Dextrose. It's top is coded light yellow
- this tube contains Oxalate/Fluoride and it's cover must be colour coded gray.

The round-seed allele would be termed as dominant. A dominant allele is always expressed. The non-dominant allele, or the recessive allele is overshadowed by the dominant. So in this case, the recessive allele would be the wrinkled-seed allele and the dominant one is the round-seed allele.
Answer:
