In Morgan’s experiment, white and yellow genes were linked tightly, while white and miniature wing were loosely linked. The percent recombination shown by these genes were
1 25% and 75 % respectively
2 1.3% and 37.2% respectively
3 98.7% and 62. 8%, respectively
4 37.2% and 1.3, respectively
Explanation:
The genes white and yellow were very tightly linked and showed only 1.3 per cent recombination while white and miniature wing showed 37.2 per cent recombination.

The salivary gland chromosomes in the dipteran larvae are useful in gene mapping because
1 These are fused
2 These are much longer in size
3 They have endore duplicated chromosomes
4 These are easy to stain
Explanation:
Endoreduplicated chromosomes are found in the salivary gland hormones in the dipteran larvae which are useful in gene mapping. These chromosomes are formed because of endoduplication or endopolyploidy or endomitosis, in this process the nuclear membrane doesn’t rupture but the chromosomes are doubled and they don’t get separated from each other.

The linked characters would always inherits together until they are
1 Delinked due to segregation
2 Masked by dominance
3 Mutated
4 Separated due to crossing over
Explanation:
The linked characters would always inherits together until they are separated due to crossing over.

Which of the following will not result in variations among siblings?
1 Independent assortment of genes
2 Crossing over
3 Linkage
4 Mutation
Explanation:
Linkage happens in al cases whenever two genes are located on the same chromosome and are close to each other. Thus, linkage has nothing to do with variation.
