In the healthy individual, the walls of the intestine are covered by intestinal villi and their microvilli, which contribute to increase the absorption surface of the nutrients we ingest and lead them to the bloodstream so that they reach the organs according to their needs.

likoan [24]

Answer: Hello your question some missing data attached below is the complete question

answer:

P( first child having PKU ) 0.25 ≤ x ≤ 0.5

Explanation:

The pedigree father has PKU ( pp ) ( From the top right )

pedigree mother = PP

The possible resultant progeny = Pp

Resultant progeny marries non-carrier ( Pp x PP ) = PP , PP, pP, pP

Hence B is either ; PP ( non carrier ) or Pp ( carrier )

one of the Resultant progeny = pp ( affected ). this simply means pedigree parents where both carriers or sufferers i.e. Pp or pp

Hence A is either ; Pp or pp

The probability of their first child having PKU

= PP x Pp = PP, Pp, PP, Pp ( probability = 0 in this case )

= Pp x Pp = PP, Pp, pP, pp ( probability = 1/4 * 100 = 25% )

= Pp x pp = Pp, Pp, pp, pp ( probability = 2/4 * 100 = 50% )

P( first child having PKU ) 0.25 ≤ x ≤ 0.5

lets denote dominant Gene = PP, recessive Gene = pp
