,
,How many chromosomes and what type of chromosomal distribution do "seedless" fruit and vegetables
have?
odd-numbered allopolyploidy
How is aneuploidy different from polyploidy?
Aneuploidy occurs when one or more chromosomes are lost or gained relative to the normal euploid
number. Polyploidy is the presence of three or more sets of chromosomes in the nucleus of an
organism.
What are the mechanisms by which aneuploidy and polyploidy are caused?
The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in
nature can result either from the duplication of euploid chromosome sets from a single species or from
the combining of chromosome sets from different species.
T/F
A cross between a tetraploid and a diploid member of the same species will produce offspring that can
undergo sexual reproduction.
False
Which of the following statements about allopolyploid individuals is true?
a. They result from a mating between individuals of the same species.
b. They are generated from exposure to colchicine.
c. They can be formed when two sperm simultaneously fertilize an ovum within the same species.
d. They may be sterile and unable to produce offspring.
d. They may be sterile and unable to produce offspring.
How many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of
4 and 6 respectively?
Diploid number of 5
Cri-du-chat syndrome is a human disorder caused by which type of chromosomal defect?
terminal deletion
A chromosome has broken, and a piece of one chromosome is translocated to a nonhomologous
chromosome. This is an example of what type of chromosomal alteration?
unbalanced translocation
What structure, seen during synapsis, is indicative of a chromosome inversion?
inversion loop
, While female and male beetles both contain twenty diploid chromosomes, males have one smaller
chromosome than in females. What can be inferred from this observation?
Biological sex is determined by the presence of an X or Y chromosome.
Females have two copies of the X chromosome, so they can be homozygous or heterozygous for any
genes found on the X chromosome. Males have only one copy of the X chromosome; what term is used
to describe this inheritance state?
hemizygous
Submit
During which stage of mitosis and/or meiosis do homologs segregate?
anaphase I of meiosis
What is the mammalian transcription factor that elicits a cascade of gene transcription and
developmental events that ultimately produce male internal and external structures?
SRY
If a trait is X-linked recessive, who would express the trait?
females homozygous for the recessive allele and males hemizygous for the dominant allele
If a trait is X-linked dominant, who would express the trait?
heterozygous females and males hemizygous for the dominant allele
Red-green color blindness is an X-linked recessive disorder. A woman with normal vision whose father
was colorblind has children with a man with normal color vision. What is the probability that their first
child will be colorblind?
1/4
Which of the following is true of the gametes of a human female who has nondisjunction of her X
chromosomes in meiosis I?
The gametes contain 22 or 24 chromosomes.
If nondisjunction occurs in meiosis I of a mother, what proportion of her gametes could have been
fertilized by a normal sperm to produce a child with Turner syndrome?
1/2
During gametogenesis, what percentage of gametes would be aneuploid if the nondisjunction event
occurred during meiosis I?
100%
During gametogenesis, what percentage of gametes would be trisomic if the nondisjunction event
occurred during meiosis II?
