During a study of inheritance of two genes, teacher asked students to perform an experiment. The students crossed white eyed, yellow bodied female Drosophila with a red eyed, brown bodied male Drosophila (i.e., wild). They observed that progenies in $F_2$ generation had 1.3 percent recombinants and 98.7 percent parental type combinations. The experimental cross with results is shown in the given figure. [Note: Dominant wild type alleles are represented with (+) sign in superscript]
  1. By conducting the given experiment, teacher can conclude that
  1. Genes for eye colour and body colour are linked
  2. Genes for eye colour and body colour show complete linkage
  3. Linked gene remain together and are inherited.
  1. A and B only
  2. B only
  3. A and C only
  4. A, Band C
  1. Teacher asked to conduct an experiment on Drosophila because.
  1. The male and female flies are easily distinguishable.
  2. It completes its life cycle in about two weeks.
  3. A single mating could produce a large number of progeny flies.
  4. All of these
  1. Genes white eyed and yellow bodied located very close to one another on the same chromosome tend to be transmitted together are called.
  1. Allelomorphs.
  2. Identical genes.
  3. Iinked genes.
  4. Recessive genes.
  1. Select the correct statement regarding the given experiment.
  1. The physical distance between two genes determines strength of linkage.
  2. The physical distance between two genes determines frequency of crossing over.
  3. The two linked genes always segregate independently of each other.
  4. Both (a) and (b)
  1. Assertion: When yellow bodied, white eyed Drosophila females were hybridised with brown-bodied, red eyed males and $F_1$ progeny was intercrossed, $F_2$ ratio deviated from 9 : 3 : 3 : 1.
Reason : When two genes in a dihybrid are on the same chromosome, the proportion of parental gene combinations are much higher than the non-parental type
  1. Both assertion and reason are true and reason is the correct explanation of assertion.
  2. Both assertion and reason are true but reason is not the correct explanation of assertion.
  3. Assertion is true but reason is false.
  4. Both assertion and reason are false.
