Solution

The correct option is D The grey phenotype has a higher fitness
The grey phenotype is resistant to the pesticide or is fit to survive and reproduce in the changed environment, that is when sprayed with the pesticide as compared to Black and Brown
So, the correct answer is 'The grey phenotype has a higher fitness'

Q. Name the following:
(a) a green coloured carbonate.

Q. Assume that the coat colour in a mammal is dictated by a genetically controlled biosynthetic pathway as depicted in the diagram given.
The pigment gene 'X' makes an enzyme 'X' that catalyses the conversion of the precursor to the grey pigment (P

1

). The dominant allele 'X' produces the enzyme necessary for this conversion. Similarly a dominant gene 'Y' produces an enzyme 'Y' that controls the conversion of the P

1

to a black pigment (P

2

). On the other hand, the dominant allele 'Z' produces an active enzyme 'Z' that can completely inhibit the conversion of precursor to P

1

. In all cases, the recessive alleles respectively produce defective enzymes with no activity. All the three genes assort independently with no interference from other genes. State the colour of a make with the genotype XXyyZZ and a female with the genotype xxYYzz.

Q. Thale cress (Arabidopsis thaliana) is a small, quickly reproducing, edible plant. It has a gene locus with an allele that results in a tolerance to heavy metals, which can leech into the soil as a result of mining operations.
A genetics professor has been using a population of thale cress for a Spring semester class to practice genetic analysis skills. The professor continues using the population after a mine in started near the collection location. The professor tracks their data from year to year. The graph displays the data for the allele frequencies for a heavy metal tolerance gene. Based on the evidence, during what year was the mine built?

Most of the metals are grey in colour; which one of the following is yellow?

Q. Haemophilia and colourblindness are the disorders caused by X chromosome linked recessive gene. A woman has one X chromosome having gene for haemophilia and colourblindness.
