A diagram showing inheritance patterns of traits linked to sex chromosomes.

Only mothers pass mitDNA traits to all offspring.

Regulatory points in the cell cycle (G1, S, G2, M) that ensure proper division.

A statistical method to assess how observed data fits expected data.

Mitosis is for cell division; meiosis is for gamete production with variation.

The sequential processes in cell division: prophase, metaphase, anaphase, telophase.

Structures that attach to kinetochores to move chromosomes during mitosis.

A phase where cells are inactive in the cell cycle, not dividing.

A complex that triggers cell division; its inactivation halts mitosis.

Excessive cell division can lead to cancer; tumor suppressor genes prevent this.

The exchange of genetic material between homologous chromosomes during meiosis.

The random distribution of maternal and paternal chromosomes during gamete formation.

Somatic cells are diploid (2n), while gametes are haploid (n); zygotes are diploid (2n).

The stage where a zygote undergoes DNA replication, resulting in 2n x 2.

The process where a cell divides to produce two identical cells, both having 2n chromosomes.

An allele that expresses its trait even when heterozygous, overshadowing the recessive allele.

A genetic cross between parents that are hybrid for one trait, showing variations in one gene.

A mating experiment between organisms hybrid for two traits, revealing interactions of both genes.

A cross between an individual and a homozygous recessive to determine the genotype of the individual.

A genetic interaction where one gene influences the expression of another gene's phenotype, causing unexpected results.

Genotypes can be either autosomal (like AA) or sex-linked (like Nn), determining inheritance patterns.
