Question | Answer |
asexual reproduction | reproduction in which only one parent produces offspring and offspring is identical to parent |
fertilization | process in which a male gamete joins a female gamete to produce a new cell that develops into an organism |
mitosis | stage in the cell cycle during which the nucleus divides and genetic info is passed on |
sexual reproduction | reproduction from the union of two parents that each pass on traits to the offspring |
stages of the cell cycle | interphase, mitosis, and cytokinesis |
interphase | the longest stage of the cell cycle/ a copy of the chromosomes is made here |
cytokinesis | the membrane surrounds the two new daughter cells |
allele | different forms of a gene for a trait |
codominant | the result when two alleles are both being expressed |
DNA | genetic material of all living things |
hybrid | organism that has two different genes for the same trait (Tt) |
incomplete dominance | result when the dominant allele is only partly expressed |
meiosis | forms gamete cells with half the number of chromosomes of the parent cell |
purebred | organism that has two of the same genes for the trait (TT) |
dominant allele | is expressed even when paired with a recessive allele (V v) V=dominant |
recessive allele | is expressed only when paired with another recessive allele (v v) v=recessive |
Punnett Square | a chart used to predict the offspring from two parents |
chromosomes | found in the nucleus and stores DNA |
Gregor Mendel | father of genetics..found that an organism's genes determine the inherited characteristics |
mutation | any change in a genome or a chromosome |
replication | process of making identical copies of DNA |
ribosomes | cell structures where proteins are made |
bases on DNA | adenine and thymine, guanine and cytosine |
double helix | shape of DNA and looks like a twisted ladder |
RNA | has one strand instead of two and contains the base uracil instead of thymine |
bases on RNA | adenine and uracil, guanine and cytosine |
chromosomal mutation | affects a large number of genetic information |
gene mutation | affects only one or just a few cells |
