Answer:
He would need to cross one homzygous red (RR) and homzygous white (rr)
Explanation:
Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.
According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.
Answer:
- Hemoglobin
- Blood
Explanation:
Since Anne is 19th century scientist, she would use conservative or classical methods of detecting blood traces on a glass at a crime scene because disovery of DNA was still not done. In 1853, Dr. Teichmann developed a test (also known as Teichmann test) that aim to crystallize haemoglobin when it is heated with glacial acetic acid. Since blood as haem group (hemin) and any surface that has traces of blood would react with glacial acetic acid and form crystals which can be then detected. This was one of the breakthrough discovery of that time.
