Incomplete Dominance Monohybrid Cross
Ilya [14]

a) RR red  BB Blue and RB purple are the genotypes of flower colour in incomplete dominance.

b) 0% probability

c) There is 100% probability of purple colour flowers

d) 0% probability

Explanation:

a)If a poofkin with red flower is crossed with blue flowers:

Alleles for red colour RR

Alleles for blue colour BB

By Punnett square:

    R     R

B   RB  RB

B    RB  RB

b) genotype of red flower =  no red flower hence 0% probability

c) probability of purple flowers =  100%

d) probability of blue flowers = 0% probability

The incomplete dominance is a phenomenon in which both the genotypes are expressed in the phenotype of the progeny. It occurs when both the alleles of the gene are dominant over each other resulting into intermediate characteristic. The heterozygous progeny will be the intermediate in phenotypic characters.

The lactose (lac) operon in E. coli is an example of a repressed gene when lactose is not available in a cell. In 3-5 sentences
irakobra [83]

Answer:

Please find the detailed explanation of this statement below

Explanation:

Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.

However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.

Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
