BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342351 If two genes a and b are linked and show 20% recombination, the proportion of gametes produced in \({F_1}\) by a dihybrid ++/ab derived from a cross between ++/++ and ab /ab would be

1 \( + + 50:ab\;50\)
2 \( + + 80:ab\;20\)
3 \( + + 20:ab\;20: + a\;20: + b\;20\)
4 \( + + 40:ab\;40: + a\;10: + b\;10\)

342352 Find out the incorrect sentence:
a. Sutton and Boveri argued that the pairing and separation of a pair of chromosomes would lead to the segregation of a pair of factors they carried.
b. Theodore Sutton and Walter Boveri noted that the behaviour of chromosomes was parallel to the behaviour of genes and used chromosome movement to explain Mendel’s laws
c. Morgan found that the genes for colour of the body and colour of the eye were very tightly linked and showed only 1.3 percent recombination

342353 Drosophila melanogaster
(fruit fly) is suitable for genetical studies because :
i. It can be grown on simple synthetic medium in the laboratory.
ii. Life cycle is short (about 2 weeks)
iii. A single mating produces large number of progenies.
iv. Visible sexual dimorphisms and many types of genetical variations can be easily observed.
