50 map units 5 map units Linkage groups d. 92 ty results from a rare, sex-limited nal puberty (P) and is expressed brother Jack and his sister Beth 10 and 14. Although Bill's mother uncles (his mother's brothers) underwent normal puberty. aploid sets of e nucleolar organizers for numbers 17-20 below) Male-limited precocious puberty results autosomal allele (P) that is dominant over the allele for normal pube only in males. Bill undergoes precocious puberty, but his brother la underwent puberty at the usual time, between the ages of 10 and 14 and father underwent normal puberty, his two maternal uncles (his underwent precocious puberty. All of Bill's grandparents underwant Match the possible genotype(s) for each relative in his family below 17. Bill's genotype 18. Bill's sister Beth 19. Bill's mother 20. Bill's father e. Pp or pp aromosome. pes of genes c. pp d. PP or Pp a. PP b. Pp dominant to the allele for brown ve allele for a pigment-depositing of two doubly heterozygous black labs «ре 21. In Labrador retrievers, the allele for black coat color (B) is dominant to the coat color (b). However, if a lab has two copies of the recessive allele for a pie gene (e), it can only have yellow coat color. In a cross of two doubly heterozygo (BbEe x BbEe), what fraction of the next generation would one expect to be vello C. 1/16 b. 1/8 e. None of the above d. 1/4 a. 3/16 ing.
