Yeah it is the old syllabus, but heres how i'd answer it anyway
3)a)i) A, B, E
ii) Females in stage A are diploid, and formed from the gametes of 2 random fleas mating, A females are more likely to contain a wider variety of alleles than those in stage D.
iii) C and D are both haploid, so mitosis will produce more haploid gametes (with same number of chromosomes)
b) In prophase 1, bivalents form between homologues. This leads to the formation of chiasmata and crossing over between maternal and paternal alleles occurs (exchanging of alleles) forming varied chromosomes. In metaphase I bivalents align randomly at the equator, so random assortment occurs and resulting cells may have any combination of maternal and paternal chromosomes. In metaphase II chromosomes align randomly on the equator, so random assortment occurs and resulting cells may have any combination of maternal/paternal chromatids
c) Parental genotypes: IoIo x IoIo, IaIb x IoIo, IaIa x IoIo, IaIb x IaIa
Baby blood group: O, B, A, AB
heres the mark scheme too:
