D) 4,2,2 E) 2,1,1 Answer: A 10. In a haploid cross of m x +, which of the following linear octads is an aberrant/unusual tetrad? (A) ++++mmmm (B) ++mmmm++ (C) +++++mmm (D) mm++++mm (E) mmmm++++ Answer: C 11. The eye color of a diploid animal is normally red. Several purple-eyed strains have been isolated as spontaneous variants (mutants), and the purple phenotype was shown to be inherited Mendelian autosomal recessive in each case. To investigate allelism between

Answer 1

Answer C - +++++mmm

The parental ditype the two genotypes which match the two parental genotypes.
They align in serial manner like ++++mmmm or mmmm++++

The nonparental ditype the two genotypes which interchange the parental alleles.
They are ++mmmm++ or mm++++mm

The option C has 5 +++++ it is not possible. They always segreagte in equal manner 4+ and 4m.
So, the option C is wrong.
