1. Genes that are linked together
because they are carried by an X
3. An X-linked genetically inherited
recessive disease in which one or
more of the normal blood clotting
factors is not produced. This
results in prolonged bleeding from
even minor cuts and injuries. It
most often afflicts males.
8. A male sex cell or gamete.
10. The place in a woman’s
reproductive system where
conception usually occurs.
12. An individual who came from two
zygotes that fused together. If
one of the zygotes is male and the
other female, the individual will
most likely be a hermaphrodite.
14. The specific term for the meiosis
process in females that produces
15. The term for individuals who have
parts of both male and female sex
organs thereby making their gender
17. A female sex cell or gamete.
19. The exchange of genetic material
(DNA) between homologous
chromosomes at the beginning of
meiosis. This results in sperm and
ova with greater genetic diversity
due to a recombination of genes.
Specifically, a portion at the end
of a chromosome is broken and
reattached on another chromosome.
21. The general term for the cells in
your body that are not directly
involved with reproduction. Most
cells in multicellular plants and
animals are of this type.
22. Genes that are linked together
because they are carried by a sex
24. The place in a man’s reproductive
system where sex cells are
1. The names for the two sex
chromosomes of males.
2. The term for the number of
chromosomes in a normal somatic
cell. This number is 46 (23 pairs)
4. Genes that are on the same
chromosome and subsequently are
inherited together as a package
unless crossing-over separates
5. The release of a secondary oöcyte
from an ovary to begin its path
down one of a woman’s fallopian
tubes to the uterus in preparation
6. The kind of cell that is formed
when a sperm and an ovum combine
their chromosomes at conception.
It contains the full complement of
chromosomes (in humans 46) and has
the potential of developing into
an entire organism.
7. The specific term for the meiosis
process in males that produces
8. The general term for the
specialized cells in your body
that are created for sexual
reproduction. These cells are also
9. The cell division process that
occurs in somatic cells. One cell
divides into two offspring cells
that are identical to each other
in their chromosome complement.
11. Twins that share their mother's uterus during gestation but come from two different eggs fertilized with different sperm. They are not genetically identical.
13. Twins that are mostly identical
genetically because they result
from one zygote splitting into two
separate ones within a few days
15. The term for the number of
chromosomes in a normal sex cell.
This number is 23 for humans.
16. The place in a woman’s
reproductive system where sex
cells are produced and stored.
18. The general term for the cell
division process in specialized
tissues of ovaries and testes
which results in the production of
sex cells. This process involves
two divisions and results in cells
that contain only half the number
of chromosomes as somatic cells.
20. An immature female sex cell in
humans and many other animals
produced before birth and stored
in the ovaries.
23. The names for the two sex
chromosomes of females.
