Question

Traits Tribbles make two noises- they Purr (P) or they Coo (p) Tribble hair is Long (H) or short (h) Tribble fur is Brown (B) or white (b) Tribbles have Long Legs (L) or short legs (l) Tribbles tend to be Quiet (Q) or loud (q) Tribbles can have Large Noses (N) or small ones (n) Tribbles can be Fast (F) or slow (f). Cross #1 P: Pure breeding fast, long haired, purring tribble x pure breeding slow, short haired, cooing tribble F1: 100% fast, long haired, purring tribbles Backcross between the F1 and the cooing parent yields the following tribbles  25 Purring, Fast, Long Haired 25 Purring, slow, short haired 25 Purring, fast, short haired 25 Purring, slow, long haired 25 Cooing, fast, long haired 25 cooing, slow, short haired 25 cooing, fast, short haired 25 cooing, slow, long haired Cross #2 P: Pure breeding Purring, white, big nosed tribble x pure breeding cooing, brown, small nosed tribble F1: 100% Purring, Brown, Big Nosed Tribble Mating the F1 x a Cooing, White, Small Nosed Tribble yields  150 bbNnPp; 200 Bbnnpp; 50 BbnnPp; 60 bbnnPp; 45 bbNnpp; 66 BbNnpp; 10 BbNnPp; 12 bbnnpp Cross #3 P: Pure breeding Brown, Big Nosed, Quiet tribbles x pure breeding white, small nosed, loud tribble F1: 100% brown, long nosed, and quiet. Backcross the F1 to the pure recessive parent yields 113 small nosed loud tribbles, 4 small nosed tribbles, 300 completely wild type, 113 white tribbles, 23 white small nosed tribbles, 7 white loud tribbles; 318 white small nosed loud tribbles; 22 big nosed, brown, loud tribbles Cross #4 P: PPQQFF x ppqqff F1: 100% PpQqFf Selfing the F1 yields 27 P_Q_F_ : 9 P_Q_ff : 9 P_qqF_ : 9 ppQ_F_ : 3 ppqqF_ : 3 ppQ_ff : 3P_qqff : 1 ppqqff Cross #5 P: Pure breeding Long Haired, long legged, fast tribble x pure breeding short haired, short legged, slow running tribble. F1: 100% long haired, long legged, and fast Backcrossing the F1 to the recessive parent yields  35 short haired slow tribbles, 35 long haired slow tribbles, 35 long haired short legged tribbles, 35 short haired short legged tribbles, 55 completely wild type tribbles, 55 short haired tribbles, 55 short legged slow running tribbles, 55 short haired, slow, short legged tribbles. Assignment: 1. Diagram out each cross (1-5) including the Parental, F1, and F2 generations. Label each individual (genotype and phenotype) and indicate linkage (by diagraming the chromosomes) where necessary. Hint, maybe not all the genes are linked! 2. According to this limited data, how many chromosomes do you estimate tribbles have? 3. Make a genetic map of these tribble genes. You must come within +/- 3cM to the correct answer. Remember to do the math rounding all your data to one decimal place.
