| Question | Answer |
|---|---|
| The female parts of a flower are collectively called this | pistil |
| The male parts of a flower that contains the pollen | anther |
| "F" stands for this in Latin | filial |
| two identical alleles | homozygous |
| two different alleles | heterozygous |
| this law states that genes on different chromosomes are not linked to one another | independent assortment |
| one set of chromosomes | haploid |
| two sets of chromosomes | diploid |
| crossing-over occurs during this phase | prophase one |
| tetrads are formed during this phase | prophase one |
| sister chromatids separate during this phase | anaphase two |
| a pair of chromosomes of the same size that have the same genes but not necessarily the same alleles | homologous chromosomes |
| different forms of a gene (plural) | alleles |
| homologous chromosomes are lined up at the center of the cell | metaphase one |
| cytokinesis occurs, and two haploid daughter cells are formed | telophase one |
| the attachment between sister chromatids breaks | anaphase two |
| the stage in which each cell has one unreplicated copy of each chromosome | telophase two |
| the structures that sort independently | chromosomes |
| the number of eggs that results at the end of meiosis | one |
| the number of sperm that results at the end of meiosis | four |
| physical characteristics (round, wrinkled) | phenotype |
| genetic makeup (RR, rr) | genotype |
| plants that self-pollinate and produce identical offspring are called this | true breeding |
| identical copies of DNA attached by a centromere (plural) | sister chromatids |
| procedure used to determine whether an organism showing a dominant phenotype is homozygous or heterozygous | test cross |
