Document Summary

The importance of sex is variation offspring resemble parents. Heredity : transmission of traits from one generation to the next. Asexual reproduction: offspring are clones of parent, all offspring genetically identical mitosis produces 2 genetically on mitosis mutation only in identical cells. Sister genetically so as chromatids separate low to r n" w identical interphase before. Mitosis stages prophase pro metaphase: metaphase anaphase telophase cytokinesis condense nuclear envelope , spindles attach line pull up on metaphase plate apart to poles. Reproduction: offspring are, offspring are highly variable a mixture of parents. Inheritance: genes : of genes units of heredity , segments of. "s locus : gene: karyotype : from mom.

Homologous : same gene i order ( not identical ) sister same alleles identical. 46 haploid t haploid - ( n ) I meiosis mate femnale haploid for organisms cycle different species ( diploid.
