Test your understanding of genetics and chromosomal variations with this engaging quiz! Whether you're a student looking to challenge yourself or a teacher seeking to reinforce key concepts, this quiz is tailored for you.
Key Features:
- 22 thought-provoking questions
- Covers a range of topics from inheritance patterns to karyotype interpretations
- Designed to enhance your knowledge in biology
If one allele masks expression of the other allele, we have:
Recessive type of inheritance
Dominant type of inheritance
Incomplete type of inheritance
Polygenic type of inheritance
The karyotype 47XXY is an example of
Turner syndrome
Klinefelter syndrome
Down syndrome
A healthy female
Del 3q means:
Deletion of the whole chromosome 3
Deletion of short arm of chromosome 3
Deletion of long arm of chromosome 3
Duplication of the whole chromosome 3
Is it true that:
For each characteristic an organism inherits two alleles, one from each parent
The two alleles for each characteristic segregate during gamete production
Different traits are inherited dependently of each other
Different traits are inherited independently of each other
The karyotype of one patient consists of 45, X0 chromosomes. Such chromosomal alteration can be an example of:
Monosomy
Aneuploidy
Polyploidy
Trisomy
A researcher measured the amount of DNA in cells growing in the laboratory and found the quantity of DNA in a cell doubled:
Between prophase and anaphase
Between the G1 and G2 phase
During the S-phase of the cell cycle
Between the G2 phase and prophase
Karyotype 47, XY, +18 can be interpreted as:
Male with translocation of chromosome 18
Male with aneuploidy
Male with trisomy of chromosome 18
Male with triploidy and an extra chromosome 18
Unbalanced reciprocal translocation between non-homologous chromosomes:
Can be detected by karyotyping performed during interphase
Usually leads to a disease
Has usually more severe clinical impact on a carrier than a balanced reciprocal translocation
Can be detected by karyotyping during S phase
From the cross of a white rat and a black rat one we can get an offspring that is white and with black spots. This can be an example of:
Incomplete dominance
Complete dominance
Codominance
Polygenic inheritance
The genotype:
Consists of haploid number of chromosomes of an individual
Is the appearance of an individual in a given environment
Is the genetic constitution of an organism
All of the definitions are wrong
Results - t(13,14) means:
Deletion of chromosome 13 and 14
Translocation between chromosomes 13 and 14
Transversion in chromosomes 13 and 14
Translation of chromosomes 13 and 14
Is it true that:
Meiosis leads to creation of haploid cells
Meiosis takes place in somatic cells
Meiosis takes place in germinal cells
Mitosis takes place in somatic cells
Is it true that in case of autosomal dominant type of inheritance:
Disease can affect all generations of a family
The child has a 50% risk of developing a disease
The child has a 25% chance of developing the disease
The disease will only appear in men
Karyotype:
Enables detection of structural chromosomal alterations
Requires sterile conditions
Can be performed on basis of paraffin embedded tissues
Can be performed only on the basis of dividing cells
Is it true that:
Phenotype is the appearance of an individual in a given environment
Skin colour of human is an example of polygenic inheritance
Humans have 46 chromosomes in a nucleus
Chromosomal alterations can be multiploid
Klinefelter syndrome:
Has the karyotype 47XXY
Gives a male female body attributes
Has the karyotype 47XXX
The primary features are infertility and small poorly functioning testicles.
