Identify the genotype of endosperm and zygote produced by the diploid male and tetraploid female (every genome of male is A and female is B)
1 Endosperm -AA BB BB- Zygote AA BB
2 Endosperm - AAB- Zygote AB
3 Endosperm - AA BB- Zygote ABB
4 Endosperm - AB B BB- Zygote ABB
Explanation:
Diploid male (AA) produced haploid gamete (1) and Tetra ploid female produced diploid gamete (egg- BB) Male gamete A + Female gamete BB = ABB (zygote) polar nuclei (or) central cell ploidy (BBBB) A (Male gamete) + BBBB=ABBBB (Endosperm)

1 A - Suspensor cell, B - Globular Embryo, C - Haustorium
2 A - Suspensor cell, B - Heart-shaped embryo, C - Haustorium
