Total questions: 16
Worksheet time: 9mins
What is it called when two or more gene that determine different characteristics located on the same chromosome?
Multiple allele
Polygenes
Linked genes
Dihybrid cross
Linked genes are...
genes that can not be separated independently during meiosis
genes that follow the Law of Independent Assortment
2 or more genes located on the same chromosome.
genes that are located on sex chromosome
Which is NOT TRUE about linked genes?
Genes located on different locus on the same homologous chromosome
Genes located on different locus on the different homologous chromosome
Representative symbol for genotype is oblique
They do not follow the Law of independent assortment
Effect of crossing over, it will produce a slightly different gamete than a parental gamete which is known as ______________
Combination gamete
Determinants gamete
Recombinant gamete
Co-dominants gamete
The reason for new combinations of gamete in linked genes because _________________
Segregation
Recombinants
Crossing over
Independent assortment
A gene located on either sex chromosome is called _________
Autosome linked genes
Sex-linked genes
Linked genes
Sex genes
Sex linked recessive inheritance will..
only express its phenotype in male
express the recessive phenotype in homozygous female only
express the recessive phenotype in hemizygous male and homozygous female
express the recessive phenotype in homozygous male and hemizygous female
Males are more likely to suffer from a sex-linked disease or disorder because
males have less DNA
males is heterogamete
males are the weaker sex
males have 1 X chromosome, so the disorder is more likely to be expressed
Hemophilia is a recessive x-linked disorder.
Which genotype represents a female who is a carrier for hemophilia?
XHXh
XhXh
XHXH
XhY
Which genotype represents a male with hemophilia?
Polygenes is when... (choose 3)
All traits are qualitative
All traits are quantitative
All genes control the same characteristic
One characteristics is controlled by many genes (2 or more genes)
What type of inheritance is determined by multiple genes located at different loci on different chromosomes?
Polygenes
Linked genes
Codominance
Incomplete dominance
An example of polygenes is
Tongue rolling
ear lobe attachment
skin colour in humans
eyes colour in humans
Determine the sequence of genes A, B, C, and D if the distance from A-C is 17 units, A-B is 25 units, A-D is 37 units, B-C is 8 units and B-D is 12 units. The order would be as follows:
A, B, C, D
A, C, B, D
D, C, A, B
C, A, B, D
In Pisum sativum, the genes for purple colour flower (R) and round seeds (Q) are dominant over the genes for white colour flower (r) and wrinkled seed (q). Heterozygous were test crossed and the result are shown in the TABLE. Calculate the distance between flower colour and seed shape genes.
