The A and B genes are on nonhomologous chromosomes. A zygote is formed by the fusion of a sperm with the genotype AB and an egg
Marta_Voda [28]

Answer:

AB, ab, Ab and aB

Explanation:

The zygote has the genotype <em>AaBb </em>because it was formed by the fusion of a sperm cell <em>AB</em> and an egg <em>ab</em>.

During meiosis the diploid <em>AaBb</em> germ cell will reduce its chromosome number by half, producing a total of 4 haploid daughter cells (the gametes, in males the sperm cells) with just one allele per gene. The genes <em>A </em>and <em>B</em> are on different chromosomes, so they assort independently, and 4 types of gametes can therefore be produced: <em>AB, Ab, aB </em>and <em>ab</em>.
