A certain type of grass has a diploid chromosome number of 8. A similar species of grass has a diploid chromosome number of 10. Interspecific hybridisation between the two species results in sterile hybrids that can, nonetheles, reproduce vegetatively. The diploid chromosome number of these hybrids would be

Text Solution

Verified by Experts

The correct Answer is:
A
The cross between these species can be represented as follows:
`{:("Grass A",,"Grass B",),((2n=8),,(2n=10),),(" "darr,," "darr,),("Gametes",,"Gametes",),((n-4),,(n=5),),(," "xx,,),(," "darr,,),(,"Sterile hybrid",,),(," "(2n=9),,):}`

Study the following statements and select the incorrect ones. (i) Pyramids of energy and yearly biomass production can never be inverted, since this would violate the laws of thermodynamics.
