X-chromosomes of female in a sex- linked inheritance case can be passed on to
1 Only female progeny
2 Only male progeny
3 Only in grand daughter
4 Male and female progeny
Explanation:
The X-chromosome of a female in a sexlinked inheritance case can be passed on to both male and female progeny. This is because females have two \(\mathrm{X}\)-chromosomes (XX), and they can pass on either of their X-chromosomes to their offspring, regardless of whether they are male or female.

The fruit fly Drosophila melanogaster was found to be very suitable for experimental verification of chromosomal theory of inheritance by Morgan and his colleagues because
1 It completes life cycle in about two weeks
2 It reproduces parthenogenetically
3 A single mating produces two young flies
4 Smaller female is easily recognisable from larger male
Explanation:
The fruit fly Drosophila melanogaster was found to be very suitable for experimental verification of the chromosomal theory of inheritance by Morgan and his colleagues because it completes their life cycle in about two weeks. The short generation time of Drosophila, with a rapid life cycle of about two weeks allows for the quick observation of multiple generations and the study of inheritance.

Which of the following does NOT agree with chromosomal theory of inheritance ?
1 During gamete formation, homologous chromosomes remain together.
2 Nucleus contains are diploid
3 Somatic cells are diploid
4 Gametes carry hereditary characters
Explanation:
The statement "During gamete formation, homologous chromosomes remain together" does not agree with the chromosomal theory of inheritance because, during meiosis (the process of gamete formation), homologous chromosomes actually separate or segregate from each other. This separation is a key aspect of the theory, allowing for genetic diversity in offspring.

What will be the gametic chromosome number of a cell, if somatic cell have 40 chromosomes ?
1 10
2 20
3 30
4 40
Explanation:
The gametic chromosome number is typically half of the somatic chromosome number. So, if a somatic cell has 40 chromosomes, the gametic chromosome number would be 20 .

Which of the following statement is incorrect regarding the band region of polytene chromosome?
1 Feulgen negative area
2 Absorb ultraviolet light at \(2600 \AA\)
3 Chromonemata is tightly packed
4 Stain intensity with basic stain
Explanation:
Feulgen negative area means that a particular region on the polytene chromosome does not stain with the Feulgen stain, which is used to detect DNA. This staining pattern can provide information about the presence or absence of DNA or variations in DNA content within the chromosome.
