The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.
During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.
The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.
Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.
During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.
In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.
Answer:
eagle- chordata phylum
ladybud- Insecta class
scorpian- Arachnida class
lobster- Crustacea class
snail- Mollusca phylum
Explanation:
The organism that contains a notochord at some of its life cycle stage are called chordates and all vertebrates are chordates so eagle comes under phylum Chordata.
Insecta is the largest class of phylum Arthropoda which contains organisms which have jointed legs, exoskeleton and segmented body for example ladybird, playing mantis, etc.
Arachnids are animals which have jointed legs and in this class spider are the largest order which contains scorpions, mites, ticks, etc.
Crustaceans are invertebrates which have hard shell made up of calcium for example lobster, prawn, shrimp, etc.
Mollusks are very large invertebrate phylum which contains a soft segmented body that is usually present inside a shell made up of calcium. for example snails.
