1- A dihybrid cross was made between a true breeding maizecultivar with purple and smooth kernel and a true breeding cultivarwith white and wrinkled kernel. The F1 kernels are all purple andsmooth. The F1 plants were then crossed with a truebreeding cultivar with white and winkled kernels. The followingdata were obtained regarding phenotypes of kernels
F2 generation:Â Â Â 110 Purple andsmooth
                       90 Purple and wrinkled
                        95 White and smooth
                       105 White and wrinkled
Based on the comparison of your calculated Chi-square value andthe Chi-square value in the table, does the inheritance of thosegenes in maize follow the law of independent assortment?
Group of answer choices
No
Yes

Chloroplasts are transmitted only through the cytoplasm of theegg in plants. In four o’clock flower plants, green phenotype isdue to the synthesis of chlorophyll by normal chloroplasts,whereas, white phenotype is due to chloroplast’s that carry mutantallele that diminishes green pigmentation. What would be thephenotypes of the offspring if you cross a variegated plant (asfemale parent) with a green plant (as male parent)?
Group of answer choices
Green, white, and variegated
Green
White

41. Myoclonic epilepsy and ragged-red fiber (MERRF) is anextremely rare disorder that affects neuromuscular systems. MERRFresults from a mutation in mitochondrial DNA (mtDNA) that impairsprotein synthesis, oxygen consumption, and energy production. Whena normal male and an affected female reproduce, which of thefollowing best predicts the expected phenotypic ratios of theoffspring?
Group of answer choices
All offspring will be affected
One-fourth of the offspring will be affected
None of the offspring will be affected
