Evolution — practice question

The puma, Puma concolor, is native to North and South America. Fig. 5.1 shows a puma. Fig. 5.2 shows the puma species' distribution.
(a)[4]

Explain how the different subspecies of puma came about.

(b)[3]

Outline how practical techniques could be used to carry out a genetic analysis of the puma species.

(c(i))[2]

Predict, with reasons, whether these phenotypic features display a continuous pattern of variation or a discontinuous one.

(c(ii))[3]

Explain how the small size of the Florida population led to a high frequency of these normally rare variant forms.

(c(iii))[2]

In 1995, eight puma females from Texas were introduced to Florida to boost breeding success and the future size of the puma population in Florida. Over the next 20 years the population increased substantially. Suggest why the introduced females were taken from Texas rather than from points A or B on Fig. 5.2.
