Explanation / Answer
Ans 25.) The correct option is A. We can expect one Y chromose in normal human males.
-Human males are having one X and one Y chromosomes. X comes from mother and Y from father.
26.) Option C is the correct answer. The chromosome 1 that you have inherited from your father and chromosome 1 that you ave inherited from your mother are considered as hoologus chromosomes.
-Homologus chrmosomes are a set of mternal and paternal chromosome that pair up with each other during meiosis inside a cell.
27.) Option B is the correct answer. After DNA repliccation, the two copies of DNA that are attatched to the same chromosoes are called sister chromatids.
-Sister chromatids which are formed by the DNA repliction are two identical copies which are joined by a common centromere. These two sister chromatids together forms a chromosome.
28.) Opion C is the corret answer. The genetic exchange of genetic material between chromosmes normally occurs during propase I of meiosis.
-The exchange of genetic matrial occurs between two homologus chromosomes during the pachytene stage of prophase I and this resuts in recominant chromosomes.
