BIO 0005 Test #2

The cell cycle is a sequence of events during which a cell prepares to divide into daughter cells into sister chromatids into gamets into homologous chromosomes( into daughter cells, into sister chromatids, into gamets, into homologous chromosomes ).

During interphase, chromatin is still uncondensed forming homologous chromosomes condensed not contained in nucleus anymore( still uncondensed, forming homologous chromosomes, condensed, not contained in nucleus anymore ).

Metaphase II; contains; 46 92 23( 46, 92, 23 ) chromosomes and 92 46 23( 92, 46, 23 ) DNA strands.

Anaphase II; contains; 46 92 23( 46, 92, 23 ) chromosomes and 92 46 23( 92, 46, 23 ) DNA strands.

Telophase II; contains; 46 92 23( 46, 92, 23 ) chromosomes and 92 46 23( 92, 46, 23 ) DNA strands.

Adaptation Evolution Natural selection Mutation( Adaptation, Evolution, Natural selection, Mutation ); features of an organism with a selective advantage.

In a pair of chromosomes sister chromatids chromatids homologous chromosomes non-identical( chromosomes, sister chromatids, chromatids, homologous chromosomes, non-identical ), there are two chromatids chromosomes sister chromatids homologous chromosomes non-identical( chromatids, chromosomes, sister chromatids, homologous chromosomes, non-identical ) united in the center by a centromere.
Sister chromatid chromosomes chromatids non-identical homologous chromosomes( Sister chromatid, chromosomes, chromatids, non-identical, homologous chromosomes ) is only used during cell division when the structures are in an X-shape (when there are two copies connected by a centromere.
When a centromere joins two non-identical chromosomes chromatids sister chromatid homologous chromosomes( non-identical, chromosomes, chromatids, sister chromatid, homologous chromosomes ) copies of a chromosome (one from each parent); they are called homologous chromosomes chromosomes chromatid sister chromatid non-identical( homologous chromosomes, chromosomes, chromatid, sister chromatid, non-identical ).

Multiple alleles Pleiotropic genes Polygenetic traits Multifactorial traits( Multiple alleles, Pleiotropic genes, Polygenetic traits, Multifactorial traits ); a trait that is controlled by more than two different alleles.
Pleiotropic genes Multiple alleles Polygenetic traits Multifactorial traits( Pleiotropic genes, Multiple alleles, Polygenetic traits, Multifactorial traits ); have effects on multiple seemingly unrelated traits.
Polygenic traits Multiple alleles Pleiotropic traits Multifactorial traits( Polygenic traits, Multiple alleles, Pleiotropic traits, Multifactorial traits ); controlled by two or more sets of alleles.
Multifactorial traits Multiple alleles Pleiotropic genes Polygenic traits( Multifactorial traits, Multiple alleles, Pleiotropic genes, Polygenic traits ); controlled by two or more sets of alleles as well as environmental factors.

Mutation Natural selection Artificial selection Sexual selection( Mutation, Natural selection, Artificial selection, Sexual selection ); produces new alleles which may provide a selective advantage.
Natural selection Mutation Artificial selection Sexual selection( Natural selection, Mutation, Artificial selection, Sexual selection ); environmental factors provide differences in reproductive success.
Artificial selection Mutation Natural selection Sexual selection( Artificial selection, Mutation, Natural selection, Sexual selection ); selective breeding for individuals who only have specific desirable features.
Sexual selection Mutation Natural selection Artificial selection( Sexual selection, Mutation, Natural selection, Artificial selection ); selective breeding of individuals of one sex for certain characteristics in the other sex.

Cytokinesis II; contains 23 46 92( 23, 46, 92 ) chromosomes (in each cell) and 23 46 92( 23, 46, 92 ) DNA strands.

When true-breeding tall stem pea plants are crossed with true breeding short stem pea plants. all of the F1-generation F2-generation G1-generation G2-generation( F1-generation, F2-generation, G1-generation, G2-generation ) plants, and 75% of the F2-generation F1-generation G1-generation G2-generation( F2-generation, F1-generation, G1-generation, G2-generation ) plants have tall stems.
