A) 3/4 lue and 1/4 oeange gene eces ?1/2 blue and i/2 orange gene eggs C) An indeterminate frequency of blue and eeange gme eggs D) Only blae gene eges E) Only oeange gene egg 12) A female with a paternal set of one eange and one long gme cheomosomes and a c maternal set 12) comprised of one blue and one shont gene cheomosome is expected to produce which of the ollowing types of eggs afher meiosis? A) Each egg has a 304 chance of having Nue long, blue short, orange long or orange shor 8) Half the eges will have maternal and half will have patemal combinations C) Each egg has 1/4 chance of having blue Jong, lue short, orange long or orange shoet combinations D) All eggs will have maternal types of gene combinations E) All eggs will have paternal types of gene combinationsExplanation / Answer
8. D. Haploid; and chromosomes of each chromosome consists of two chromatids.
During meiosis I homologous chromosomes separate which reduce chromosome number from diploid to haploid but each chromosome at this stage consists of two chromatids.
9. A. I.
Synapsis and Crossing over takes place during prophase I of meiosis .
10. E. VII .
sister chromatids separate during Anaphase II .
11. B. 1/2 blue and 1/2 Orange gene eggs.
