Question

(9 pts). In the mouse, the genetic linkage among 3 gene loci isbeing studied. The loci are not part of a sex chromosome (e.g. X orY); but, they may be part of the same autosome. There are twoalleles at each locus. At the hair locus, allele H is for hairy, and h is for thehairless phenotype. At the ear locus, allele E isfor big, and e is for small. At the tail locus,allele T is for long, and t isfor short. Upper case alleles are completely dominant to theirrespective lower case allele. No interactions.

Kahn, a hairy, long-tailed,big-eared male mouse was mated with female mice, all hairless,short-tailed and small-eared. Those matings produced 900 childrenas described in the table below

Class #	Phenotypic Class ofChildren	Number ofchildren
1	Hairy, big ears,long tail	300
2	Hairy, big ears,short tail	7
3	Hairy, small ears,short tail	66
4	Hairy, small ears,long tail	72
5	Hairless, smallears, long tail	12
6	Hairless, big ears,short tail	67
7	Hairless, smallears, short tail	310
8	Hairless, big ears,long tail	66
total		900

a._______________: If the 3loci were segregating independently of each other, how manychildren would be expected in the genotypic class,
