Light-response curves of photosynthetic carbon fixation in sun and shade plants. Typically, shade plants have a low light compensation point and have lower maximum photosynthetic rates than sun plants this is because respiration rates in shade plants are very low; which of the following graph is correct?

In this pedigree II 3 and III 1 are affected with an X-linked recessive disorder which is tightly linked to a marker locus with alleles A and B, with a recombination fraction of 0 between the disease and marker loci. Analysis of the linked marker results indicates that the disease must be segregating with:

In this pedigree I 1 and II 2 have Becker muscular dystrophy which shows X-linked recessive inheritance. III 2 has oculocutaneous albinism which shows autosomal recessive inheritance with an incidence in the general population of 1 in 10 000. The disease status for both Becker muscular dystrophy and oculocutaneous albinism is unknown for IV 1 and IV 2.

What is the probability that III 3 is a carrier of Becker muscular dystrophy?
