Question 12 Consider a large population of fish in a lake who reproduce in discrete generations by a process of random matching. The colour of [he fish is controlled by a single gene. Doubly dominant fish TT ancl heterozygotes Tt are silver; homozygous recessives tt are, orange. 111 Lhe population as a whole it is observed that the silver fish outnumber thc orange fish in the proportions 11:5. (a) What proportion of the population are heterozygotes? (b) What proportion of the silver fish are heterozygotes? (c) An orange, fish and a silver fish of opposite sexes are, selected at. random. If they produce an offspring, what, is Lhe probability t.hat, it will be orange? A random selection of silver fish are caught and moved to a new empty lake. The fish in this new lake continue to reproduce. in discrete generations by a process of random matching. After several generations it is observed that around one in eight fish in the new lake are orange. (d) Does this observation accord with expectations? (e) What proportion Of all t alleles in the new pond occur in orange fish?
