What is the evolutionary significance of parthenogenesis in the Class Insecta?

Given that the first division of the zygote divides the embryo into the future right and left halves of the butterfly, complete a hypothesis that explains how nondisjunction during the first mitosis might have produced this unusual-looking butterfly. Match the terms In the left column to the approprlate blanks In the sentences on the right. Not all terms will be used. Reset Help female The zygote has the genotype. If nondisjunction occurs during the first mitosis the left cell will have the genotype and develops to the half. The right half. daughter cell will have the genotype and develops to the XXXX XX male XXX XY

In embryophytes, especially spermatophya, what is the difference between a "sporocyte" (e.g., megasporocyte) and the actual spore (e.g., megaspore)? a) Meiosis: Megasporocyte is still diploid, megaspore haploid b) Mitosis, number of nuclei: Megaspore has eight cell nuclei, megasporocyte only one c) Cytokinesis: Megasporocyte has only one cell, Megaspore can have several (as endosporic gametophyte). d) None: the two terms are synonymous. e) Meiosis: Megaspore is still diploid, megasporocyte haploid
