<u>Colony morphology on agar</u> is NOT a phenotypic test.
Examples of phenotypic tests are;
- Antibody reaction
- Antibiotic resistance profile
- Gram staining
Explanation:
Colony morphology is the visible shape taken by a colony of microorganisms. Phenotype, on the other hand, is the external traits of an individual organism based on its genotype and environmental influence. Colony morphology is not determined by the genotype of the organisms hence can't be considered a phenotype trait.

1. If we cross YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits)
P: YyLl x yyll
F1 generation: YyLl: 400 Yyll: 100 yyLl: 100 yyll: 400
Recombinant offspring are those children whose genes contain a non-parental allele combination (neither allele group is directly inherited from either parent). This happens when genes are located on the same chromosome but are so far apart from one another so that their alleles get crossed over during meiosis. In this case, Yyll and yyLl are the recombinant.
2. Calculation of distance between Y and L.
The numbers of the two recombinant types is 200 (100 Yyll + 100 yyLl) and 800 parental offspring.
Total number of offspring is 1000.
So: 200/1000*100=20 map units.
There is 20 percent recombinant offspring frequency.
Answer:
The sun is about 10,000 degrees Fahrenheit or 5,000 degrees Celsius! :)
Answer:
____Large molecules, regardless of their polarity____ are particularly polarizable.
Explanation:
All the large molecules are called polar molecules because they have many bonds including ionic bond, Van der Waals forces or hydrogen bond and flexibility in conformation. This property also increase the boiling point of large molecules.
