This is a presentation including all of the vocab words for Holt Modern Biology chapter 12. It includes both sections one and two.

1. Holt Modern Biology Textbook

2. 
a chromosome that determines the sex of an
individual
(We can see that
this karyotype
codes for a male)


3. 
Any chromosome that is not a sex
chromosome

4. 
a trait that is determined by a gene found on
one of the sex chromosomes, such as the X
chromosome or the Y chromosome in
humans

5. 
One of a pair of genes that tend to be
inherited together

6. 
A diagram of gene positions on a
chromosome

7. 
in chromosome mapping, an increment of 1
percent in the frequency of crossing-over

8. 
mutation that occurs in an organism's
gametes

9. 
A mutation that occurs in a body cell

10. 
a gene or chromosomal mutation that
influences the development of an organism in
such a way that the organism cannot survive

11. 
Loss of a part of DNA from a chromosome

12. 
a kind of mutation in which the order of the
genes in a section of a chromosome is
reversed

13. 
an exchange of chromosome parts

14. 
meiosis in which there is a failure of paired
homologous chromosomes to separate

15. 
gene mutation involving changes in one or a
few nucleotides

16. 
A mutation in which a nucleotide or a codon
in DNA is replaced with a different nucleotide

17. 
mutation that shifts the "reading" frame of
the genetic message by inserting or deleting
a nucleotide

18. 
a mutation in which one or more nucleotides
are added to a gene

19. 
A diagram that shows the occurrence of a
genetic trait in several generations of a family

20. 
an inactive substance that is a vehicle for a
radioactive tracer of the same substance and
that assists in its recovery after some
chemical reaction

21. 
an abnormal condition that a person inherits
through genes or chromosomes

22. 
of or relating to an inheritable character that
is controlled by several genes at once

23. 
characters that are influenced strongly both
by the environment and by genes

24. 
genes with three or more alleles

25. 
situation in which both alleles of a gene
contribute to the phenotype of the organism

26. 
one allele is not completely dominant over
the other allele

27. 
an autosomal trait that is influenced by the
presence of male or female sex hormones

28. 
A human genetic disease caused by a
dominant allele; characterized by
uncontrollable body movements and
degeneration of the nervous system; usually
fatal 10 to 20 years after the onset of
symptoms.

29. 
Technique that allows a physician to remove
from the amnion, the sac that surrounds the
fetus, between the 14th and 16th week of
pregnancy

30. 
Sampling of cells derived from the zygote
that grow between the mother's uterus and
placenta between the 8th and 10th week of
pregnancy

31. 
Guidance for prospective parents on the
likelihood of genetic disorders in their future
children

32. 
The insertion of working copies of a gene into
the cells of a person with a genetic disorder in
an attempt to correct the disorder

33. 

the exchange of genetic material between
homologous chromosomes during meiosis
can result in genetic recombination
