BIO 260-Sex Linkage
1. Species: Sex determination methods differ by:
2. Genetics and/or the environment: Sex in a species can be determined by:
3. temperature, pheromones, pollution, parasites: What environmental factors can affect sex?
4. XX chromosomes in females, and XY chromosomes in males: In humans and
drosophila, sex is determined by:
5. ZW chromosomes in females, and ZZ chromosomes in males: In birds and butterflies.
sex is determined by:
6. XX chromosomes in females, and X0 chromosomes in males (or X-mono-
somy): in moths, sex is determined by:
7. The ploidy of their cells. Females are diploid, males are haploid.: In bees and wasps,
sex is determined by:
1/3
, 8. The temperature of the environment when eggs are incubating, they will turn
female if incubated in cool temperatures and turn male if incubated in warm
temperatures: in lizards and crocs, sex is determined by:
9. Age, older adults become females and younger adults become males. If the
a male, then
female dies, the male will become female: In anenome fish, sex is determined by:
10. Protandry: a form of sequential hermaphroditism in which the individual matures first as
transforms into an adult female later in life
11. Heterogametic Sex: the sex that has 2 different sex chromosomes
-2 diff. gametes
12. Homogametic Sex: The sex that has two of the same chromosome
13. X;Y: The chromosome is similar to the chromosome (not vice versa) found on both the
h each other during
2/3
