Cell Cycle And Meiosis Flashcards
Reproductive mode by which offspring arise from two parents and inherit genes from both
Sexual reproduction
Shared traits of sexual reproduction
Genetics, Heredity and Variaton
Is the scientific study of heredity and variations
Genetics
Is the transmission of traits from one generation to the next
Heredity
It is demonstrated by the differences in appearance that offspring show from parents and siblings
Variation
Occurs in immature reproductive cells (germ cells) of sexually reproducing eukaryotes, forming make and female haploid gametes
Meiosis
Sorts the chromosomes into new nuclei twice (meiosis I and meiosis II)
Meiosis
Mature, haploid reproductive cell
Gamete
Having one of each type of chromosome characteristic of the species
Haploid (n)
Is restored at fertilization, when two haploid (n) gametes fuse to form zygote
Diploid number
Fusion of a sperm nucleus and an egg nucleus, resulting in a single-celled zygote
Fertilization
First cell of a new individual, with two sets of chromosomes, one from each parent
Zygote
Two new nuclear envelopes form around the two clusters of still-duplicated chromosomes
Meiosis I
Separates sister chromatids; four haploid nuclei typically form, each with one complete set of unduppicated chromosomes
Meiosis II
