What is the phenotype of the offsprings born to a woman with normal vision (homozygous) and a colourblind man?
1 All the sons are with nomal vision and the caughters are colorblind
2 All the sons and daughers are with normal vision
3 All the sons and daughters are colorblind
4 All the sons are colorblind and the daughters are with normal vision
Explanation:
: The normal mother (XX) would transtrit the rormal X chromosomes to all of her daughters and son: hence all sons and daughters will be normal but daughter would then serve as carrier.

If haemoglobin ( \(\mathbf{H b}\) ) of a normal individual and a sickle-cell patient are run in electrophoretic field, they will show
1 same mobilities
2 different mobilities
3 Hb of patient will not nove at all
4 Hbs are immobile
Explanation:
: In trormal haemoglobin electrophoresis red cell lysates are subjected to electric fields under alkaline gel and acid gel pH . A change in the amino acid composition of the globin chains results in alteration of the charge of the hamoglobin molecule, resulting in a change of the speed of migration, but in the haenoglobin of sickle cell patient does not show this type of electrophoresis. Thus, on gel electrophoresis, the haemoglobin molecules of persons with sickle cell anaemia migrated at a different rate and thus, ended up at a different place on the gel, from the haemoglobin of trormal persons.

Occurrence of an extra chromosome in a diploid set of chromosome is called
1 monosony
2 polysome
3 trisony
4 polyploidy MBT CET-07.10.2020 Shift-I
Explanation:
: Dccurrence of an extra chromosome in a diploid set of chromosome is called trisomy (2n) they are specifically useful in locating genes on specific chromosomes. Klinefelters syndrome and down syndrome are disorders occurs due to trisony.

Genetic counsellors can identify heterozygous individuals by:
1 height of individuals
2 colour of intividuals
3 screening procedures
4 all of the above
Explanation:
: Genetic counsellors can identify heterozygous individuals by screening procedures. Genetic screening is a part of genetic counseling which includes parental diagrosis, carrier diagrosis and predictive diagnosis. Genetic counsellors use screening procedure. Genetic counseling is giving of information and advice about the tisk of genetic disease.

Dominant lethal gene is one which:
1 allows the organistr to survive but not reproduce
2 determines sex of off springs
3 allows the organism to survive and reproduce
4 kills the organism
Explanation:
: Dominant lethal gene is one which kills the organism. Certain genes are absolutely essential for survival. The alleles created by mutations in these genes are called lethal alleles. The phemotypic manifestation of these alleles is the death of the organism. Dominant lethal alleles show lethal effects even in heterozygous conctition. Primiple of Inheritance and Variation
