D.   In an animal life cycle, zygote divides by mitosis to develop into a multicellular organism.

A.   Plants and some algae exhibit an alternation of generations in their life cycles.

B.   In an animal life cycle, meiosis produces gametes (n). Gametes are the only haploid cells in animals. In an animal life cycle, zygote divides by mitosis to develop into a multicellular organism. Plants and some algae exhibit an alternation of generations in their life cycles. In the life cycles of plants and some algae, the diploid sporophyte, makes haploid spores by meiosis. In most fungi and some protists, the only diploid stage is the single-celled zygote; there is no multicellular diploid stage. and; The haploid adult in fungi and plants produces gametes by mitosis.

C.   In the life cycles of plants and some algae, the diploid sporophyte, makes haploid spores by mitosis and the haploid adult in fungi and plants produces gametes by mitosis.

D.   In the life cycles of plants and some algae, the diploid sporophyte, makes haploid spores by meiosis and in an animal life cycle, zygote divides by mitosis to develop into a multicellular organism.

E.   In an animal life cycle, meiosis produces gametes (n). Gametes are the only haploid cells in animals

F.   In early prophase I, each chromosome pairs with its homolog and crossing over occurs and during Meiosis II, the number of chromosomes is reduced by half and genetic variation is produced

A.   During Meiosis II, the number of chromosomes is reduced by half and genetic variation is produced

B.   Meiosis is preceded by the replication of chromosomes and during Meiosis II, the number of chromosomes is reduced by half and genetic variation is produced.

C.   Meiosis is preceded by the replication of chromosomes, in early prophase I, each chromosome pairs with its homolog and crossing over occurs, in anaphase I, pairs of homologous chromosomes separate, and at the end of meiosis I, the number of chromosomes is reduced by half and genetic variation is produced.

D.   At the end of meiosis I, the number of chromosomes is reduced by half and genetic variation is produced.

A.   Mutations refer to the changes in an organism’s DNA. Mutations are the original source of genetic diversity. Mutations create different versions of genes called alleles.

C.   Mutations create different versions of genes called alleles.

D.   Mutations are the original source of genetic diversity. Crossing over is a form of mutation.

E.   Crossing over is a form of mutation.
