In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance

igomit [66]

Answer:

The correct answer is -

a. 7

b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc

c. p7 is abundant

Explanation:

According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :

p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7

p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6

p5p5, p5p4, p5p3, p5p2, p5p1 - 5

p4p4, p4p3, p4p2, p4p1 - 4

p3p3, p3p2, p3p1 - 3

p2p2, p2p1 - 2

p1p1- 1 least dominant

Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.

Escherichia coli, abbreviated as e. Coli, are bacteria found in the environment, foods, and intestines of people and animals. Wh

E. coli belongs to the genus Escherichia

Taxonomically, <em>Escherichia coli </em>is categorized as belonging to the phylum Proteobacteria, class Gammaproteobacteria, family Enterobacteriaceae, order Enterobacteriales, and genus Escherichia (named after its discoverer, Theodor Escherich).

Escherichia coli (E. coli) are typically found in warm-blooded organisms' lower intestines. The majority of E. coli strains are not harmful, but some can seriously poison food.

A Shiga toxin-producing E. coli (STEC) is capable of causing severe foodborne illness.

Raw or undercooked ground meat products, raw milk, and fecal contamination of vegetables are the most common causes of STEC outbreaks.

The illness is usually self-limiting, but it can progress to a potentially fatal condition like haemolytic uraemic syndrome (HUS), especially in young children and the elderly.
