A.
a chart used to show all the ways genes from two parents can combine
and be passed to offspring
B.
a female reproductive cell that has just a single copy of the genetic
material of the parent
C.
a male reproductive cell that has just a single copy of the genetic material
of the parent
D.
a part of sexual reproduction in which cells divide to form sperm cells in a
male and egg cells in a female
E.
a sperm or egg cell, containing half the usual number of chromosomes
(one chromosome from each pair); found only in reproductive organs
F.
an alternate form of a gene for a specific trait or gene product
G.
describes a gene that is not expressed when combined with a dominant
form of the gene
H.
describes the gene that determines the phenotype of an individual when
two different copies are present in the genotype

the basic unit of heredity that consists of a segment of DNA on a
chromosome

a ratio that states the number of times an outcome is likely out of a
possible 100 times

combine to form offspring with genetic material from both

produce offspring that have these traits
18. ______ genetic engineering
19. ______ genome

genetically identical to its one parent
20. ______ mutation
D. the scientific process in which DNA is separated from an organism,
changed, and then reinserted into the same or a different organism
21. ______ pedigree
22. ______ replication
E. All the DNA of an organism, including its genes; the genetic material of
an organism.
23. ______ RNA
F. a molecule that carries genetic information from DNA to a ribosome,
where the genetic information is used to bring together amino acids to
form a protein
24. ______ selective breeding
G. a chart that shows family relationships, including two or more
generations
H. any change made to DNA
