Question

On the planet susru, there are three types of bears; those who like honey-nut cheerios, those who like multi-grain, and those who like plain cheerios. the phenotype is determined in an epistatic way by two loci:

Answer 1

The dominant mode way of inheritance ratio is 12:3:1
12/16 = 0.75 = 75% = 801 or we can say phenotype :honey-nut and genotype:HHMM, HhMM,HHMm, HhMm,Hhmm
3/16 = 0.1875 = 18.75% = 200 or
phenotype: multigrain and genotype: hhMM, hhMm
So if we can say that 75% is 801, what about 100%
75% = 801
100%=?
100×801/75=1068
(1/16) ×1068 = 67 which is expected but observed is 55 for example
honey nut the observed is 801 and expected is 801.
multigrain the observed is 200 and the expected 200.
plain the observed is 55 and the expected is 67 

Answer 2

Answer:

Honey Nut: with alleles H (dominant) h (recessive)

Multi-Grain: with alleles M (dominant) m (recessive)

HHMM Bear and a hhmm bear cross, and the F1s like honey nut. A cross of two F1 bears will produce the following sums two-locus genotype counts:

All F2 Bears with at least one H allele: 801

All F2 Bears with at least one M allele: 200

55 is the number of bears that is consistent with a dominant mode of inheritance at the 1% level of significance.
