How many types of gametes are produced when linkage is complete and the diploid number is 2? What process produces haploid gametes? What are male reproductive cells, or gametes, called? Define Gametes. What is the term for the cells that will eventually undergo meiosis to produce gametes?
as well as review some of the related concepts from animals that are often used in discussions of plant sexuality. Most animal species fit within a two-sex model in a haplobiontic life cycle. Here gametic meiosis is done, followed immediately in the life cycle...
What type of alleles will a pure plant have? What are two types of selective breeding? Plants that produce their gametes in flowers are called In plants, what is the diploid form called? Do seed-bearing plants produce spores? Do seed-bearing plants have protostele?

Step-by-Step Solution:1. Definition of Heterospory: - Heterospory refers to the production of two distinct types of spores: microspores (male spores) and megaspores (female spores). This phenomenon is observ

Complete crossover suppression between sex chromosomes, however, is not advan- tageous because some pairing is required for precise disjunction during male meiosis (Koller & Darlington, 1934). This necessity for X-Y pairing accounts for the presence of a homologous segment between the human X and...
(2) what is the frequency of double-reduction ? Indeed, two sister chromatids could segregate in the same gamete after formation of a tetravalent during meiosis. Consequently, double-reduction creates new types of gametes and modifies the probabilities of each type of gametes in a segregating ...
Macrochromosomes tend to have lower recombination rates (per Mbp) than microchromosomes, presumably because all chromosomes have an obligate crossing-over during meiosis, even if they are physically short (Groenen et al., 2000; Stapley et al., 2008). Within macrochromosomes of zebra finches, ...
