Which term describes the example below?A child with no freckles has a mother who has freckles and is heterozygous and a father w
Natali5045456 [20]
It is C as to have freckles you have to have a dominant and recessive gene (can be worked out using a punnett square) as the child has 50% of not having freckles like his dad or 50% having freckles like his mom. 
                     male genes(homozygous recessive)
                     f            f

female    F    Ff           Ff
genes
              f     ff             ff

so ff is not having freckles and being homozygous recessive, or Ff having freckles and being heterozygous.

So the child is heterozygous  so C

These were developed by Phoebus Aaron Theodor Levene ,he was a russian who studied medicine, with keen interest in organic chemistry.

He migrated to the US in 1891, and started practising medicine  in 1892.Due to his strong interest in research he combined research(1894) in  molecular structure of sugars with medical practice,But this was cut short when he contracted tuberculosis.

Between 1896- 1906,he collaborated with many nucleic acids  and protein exoperts  e.g Albrecht Kossel and Emil Fischer to  wok on the structure of DNA.And headed the Rockefeller Institute for Medical Research.

He works included :the isolation of  Nucleotide-monomers of DNA

:the isolation of D-ribose sugar from ribonucleic acid molecule.(RNA)

Discovery of 2-deoxyribonucleic ,

How the components of Nucleotide(phosphate group,sugars, and organic bases) combined to form nucleotide, and how the latter undergo condensation reaction to form DNA.
