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

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.

Mitosis and cytokinesis results in the formation of __; cytokinesis results in the formation of __

4 diploid cells; 4 haploid cells

2 diploid cells; 4 haploid cells

2 diploid cells; 2 diploid cells

4 haploid cells; 2 diploid cells
