Question

Here is some data collected when two true breeding flies were crossed to produce the F F2 generation. Use parent this data to answer the following questions. Generation sex wing Body Eye e of Count type Color Color Antennae 1 Parent Male Straight Black Bar Curly Parent Female Straight Black Bar Straight 1 F1 Male Straight Black Bar Straight 49 F1 Female Straight Black Bar Curly 51 Curly Male Straight LBlack L Bar 40 Female Straight Black Bar Straight F2 Male Straight Black Bar Straight 24 F2 Female Straight Black Bar Curly 2 Recalling that wild type is tan body, red eyes, long straight wings and straight antennae, the that mutant trait

recalling that wild type is tan body, red eyes, straight wings and straight antennae, the data is consistent with the logical hypothesis that mutant trait-pick a mutant-is -autosomal or sexlinked-, -dominant or recessive-.
using the f2 geb data and assuming we want to fail to reject the null hypothesis abd support "logical" hypothesis for this mutant trait, for the chi square goodness of fit test what is the chi square statistical value? (value should be to the hundreths)

Answer 1
