Why do gametes have to be haploid instead of diploid?

What are the structures in plant life cycke that are haploid?

What is endopolyploidy? What is its biological significance?

how many chromatids do tetrads have and where do they form

When the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. Based on the diagram, how many unique ascospores are produced in each ascus resulting from the cross fertilization of two Ascomycetes fungi?   A. 1 B. 2 C. 4 D. 8

Diploid = 2n with n being # of chromosomes so, a) Haploid = n b) Haploid = 3n

What would happen to the chromosome number in gametes and offspring if ​gametes were formed by the mitotic process instead of the meiotic process?

in what meitotic phase we can identify bridge abberation? anaphase I or Metapahse I?

When the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true? A. The trait for spore color is determined by exactly one gene. B. The trait for spore color is determined by more than one gene. C. The allele for black spores is dominant over that for white spores. D. The allele for white spores is dominant over that for black spores.

What is the haploid and diploid chromosome number in the cell below?
