Question | Answer |
sexual reproduction | reproduction from the union of two parents that each pass on traits to the offspring |
specialized reproductive cell | gamete |
male gamete | sperm |
process in which a male gamete joins a female gamete to produce a new cell that develops into an organism | fertilization |
stage in the cells cycle during which the nucleus divides | mitosis |
reproduction in which one parent produces offspring that is identical to the parent | asexual reproduction |
female gamete | egg |
phase of the cell cycle in which the cell grows and makes a copy of its chromosomes | interphase |
stage of the cell cycle in which the nucleus divides | mitosis |
stage of the cell cycle in which a new cell wall or membrane divides the cell | cytokinesis |
characteristics of living things | genetic traits |
structures in nucleus that store DNA | chromosomes |
different forms of a gene for a trait | allele |
result of two alleles both being expressed | codominant |
gentic material of all living things | DNA |
an organism that has 2 different genes for the same trait | hybrid |
result when the dominant allele is only partly expressed | incomplete dominance |
cell division that reduces the number of chromosomes by half | meiosis |
The "father" genetic study | Gregor Mendel |
an trait that is always expressed | dominant trait |
a trait that is only expressed when paired with another allele of the same type | recessive trait |
a tool used by scientists to predict the the outcome of a genetic cross | Punnett Square |
any change in a genome or chromosome | mutation |
process of making identical copies of DNA | replication |
cell structures where protiens are made | ribosomes |
