prentice hall biology chapter 11- Introduction to Genetics
chromosomes | ||
the scientific study of heredity | ||
the process in which the male and female reproductive cells join together in sexual reproduction | ||
organisms that produce offspring identical to themselves through self-pollination | ||
a specific chracteristic | ||
crosses between parenrts with different traits | ||
chemical factors that determine traits | ||
the different forms of a gene | ||
states that some alleles are dominant and others are reccesive | ||
separation of alleles during gamete formation | ||
sex cells | ||
the likelihood that a particular event will occur | ||
to predict the outcomes of genetic crosses | ||
a diagram that can determine the possible gene combinations | ||
organisms that have two identical alleles for a particular trait | ||
organisms that have two different alleles for the same trait | ||
physical characteristics | ||
genetic makeup | ||
states that genes for different traits can segregate independently during the formation of gametes and helps account for the many genetic variations observed in pants, animals, and other organisms | ||
when one allele is not completly dominant over another | ||
when both alleles contribute to the phenotype | ||
when genes have more than two alleles | ||
traits controlled by two or more genes | ||
term used to refer to chromosomes that each have a corresponding chromosome from the opposite-sex parent | ||
a cell that contains both sets of homologous chromosomes | ||
a cell that has one set of homologous chromosomes, a cell that has a single set of chromosomes and therefore only 1 set of genes | ||
a process of reduction division in which the number of chromosomes is cut in half through the separation of homologous chromosomes in a diploid cell | ||
(prophase)structure of chromosome paired with its corresponding homologous chromosome | ||
process in which homologous chromosomes exchange chromatids in meiosis | ||
