GUIDE TO FLORAL DIAGRAMS AND SYMBOLS. https://lnkd.in/dG89mnv View in LinkedIn

FLORAL FORMULAS. "Floral formula is a means to represent the structure of a flower using numbers, letters and various symbols, presenting substantial information about the flower in a compact form. It can represent particular species, or can be generalized to characterize higher taxa, usually giving ranges of organ numbers.” https://lnkd.in/dkxxcsV View in LinkedIn

FLORAL DIAGRAMS. "Floral diagram is a graphic representation of flower structure. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols." https://lnkd.in/dBmi9W7 View in LinkedIn

VARIANT FEATURES OF FLOWERS. "Unfortunately, good candidate genes are lacking for many of these morphological features. The one notable exception is floral symmetry, which has been studied in detail in the bilaterally symmetric (zygomorphic) flowers of Antirrhinum." https://lnkd.in/dVXk7jP View in LinkedIn

FLOWER STRUCTURE PRIMER. Just when you thought you had a handle on flowers, time to think again. https://lnkd.in/dzdtdA4 View in LinkedIn

PURGING AND UNMASKING. "That said, haploid meiotic products have the advantage of allowing the “purging” of deleterious alleles and the “unmasking” of potentially adaptive recessive alleles, both clear benefits of the modern version of meiosis." https://lnkd.in/ebVhXPf View in LinkedIn

FALSE PREMISE. "There is no basis to the claim that the original meiotic products were haploid, other than the parsimony argument that because they are so now then they may also have been so when they originated." https://lnkd.in/ebVhXPf View in LinkedIn

PLOIDY TRANSITION. "It is worth noting explicitly that original versions of meiosis may have taken tetraploids to diploids rather than diploids to haploids, or octoploids to tetraploids for that matter because the key metric is ploidy transition rather than absolute ploidy level." https://lnkd.in/ebVhXPf View in LinkedIn

UNIQUE FEATURE. "For this to succeed, mechanisms promoting sister chromatid cohesion were required. The unique feature of meiosis compared with mitosis is meiosis I in which chromosome homologs rather than sister chromatids segregate in a reductional division." https://lnkd.in/ebVhXPf View in LinkedIn

HALLMARK OF MEIOSIS. "A key innovation—indeed, the hallmark of meiosis—was synapsis between homologs." https://lnkd.in/ebVhXPf View in LinkedIn
