Consider the Pixie inheritance problem represented on Table

Consider the Pixie inheritance problem represented on Table 1. The dominant are called S, L and Y, respectively. If the gene were to unlinked best estimate of the expected number of pixie kids displaying the recessive traits (s, l, y class = black, simple, green) is: 1250 625 2500 5625 312 An \"SLY\" F1 male, the son of two pure bred (SLY times sly), marries a \"sly\" female. Their passionate union results in 10,000 kids whose phenotypic classes are listed.

Solution

sly i.e. black hair, simple wings, green body individuals are 4325. Sly i.e.silver hair with simple wings and green body individuals are 492, sLY i.e. black hair individuals with lacy wings and yellow body are 487, black hair with lacy wings and green body are 185 denoted by sLy, SlY are silver hair, simple wings and yellow body which are 196, SLy are 5 in number with silver hair, lacy wings and green body, 7 individuals are slY having black body, simple wings but green body. Thus individuals having black hair, simple wings or green body are 4325+492+487+185+196+5+7=5687. Thus the correct answer is option D which is approximately 5625 individuals having black body, simple wings or green body.
