Photograph 51 is the nickname given to an X-ray diffraction image of crystallized DNA taken by Raymond Gosling in May 1952, working as a PhD student under the supervision of Rosalind Franklin, at King's College London in Sir John Randall's group. It was critical evidence in identifying the structure of DNA.
Answer:
The tasting allele is dominant.
Explanation:
- The law of dominance states that the dominant allele will always express itself in homozygous or heterozygous conditions.
- While, the recessive allele Can express itself only in Homozygous recessive condition.
- The phenotypic ratio in case of monohybrid cross is 3:1 where i.e , about 3 out of every four offspring tends to express the dominant trait.
- According to the given statistics,80% of the population can taste PTC and 20 % cannot.
- Thus The tasting allele is a dominant allele.
Answer:
The advantages are-
*It leads to a good yield as if the parents are of good quality then the offspring will be more yielding
*They can give more than before that the parent gives.
The disadvantages-
*They are born with many typrs of diseases
*This leads to their death in early age.
The offsprings dies as theie body psrts are not fully developed.
When it lacks an F plasmid it is called F-
Homozygous is when the two letters are the same and dominance is represented by capital letters. There is one square that has two capital letter so 1/4 is equal to 25%. Hope this helps
