Inheritance Vocabulary list
1. meiosis
a. a type of inheritance in which both alleles present are fully and equally
expressed
2. homologous
chromosomes
b. chromosomes that have copies of the same genes in the same
locations
3. Genetics
c. a condition in which the alleles for a particular gene are different
4. polygenic
inheritance
d. duplicated homologous chromosomes pair up and exchange
sections of DNA during prophase of meiosis I
5. linked genes
e. homologous chromosome, in the tetrad structure, line up at the middle
of the cell.
6. autosomes
f. Sister chromatids separate from each other and move to opposite poles
7. inheritance
g. a type of inheritance in which the presence of one dominant
allele is sufficient to cause expression of the dominant phenotype
8. crossing over
h. genes that are on the same chromosome
9. sex chromosomes
i. an allele that masks the expression of the partner allele on the
homologous chromosome
10. allele
j. filial (daughter) generation, result of two parental hybrid cross.

expressed
13. mutation

dominance
s. a chromosome that does not determine gender
20. incomplete
dominance
t. the complete set of genes and alleles possessed by an individual
21. codominance
u. homologous chromosomes join together (synapse) and form a tetrad
structure that exchanges segments of DNA.

sister cells
