#Unit 8. Inheritance Biology

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?

Following statements are regarding to the wingless gene in drosophila.

A. In the cells transcribing the wingless gene, wingless mRNA is translocated by its 3’UTR to the apex of the cell. At the apex, the wingless message is translated and secreted from the cell.

B. The cells expressing engrailed can bind this protein because they contain Patched, which is the Drosophila membrane receptor protein for Wingless.

C. Binding of Wingless to Frizzled activates the hedgehog signal transduction pathway, resulting in the continued expression of engrailed.

D. Wingless protein also acts in an autocrine fashion, maintaining its own expression.

Which of the following combinations is correct?
