Question

due to mendels law of segregation
a homologous chromosomes pair up and cross over during prophase 1 of meiosis
b alleles belonging to the same gene will never end up in the same gamete during mitosis
c alleles belonging to the same gene will never end up in the same gamete during meiosis
d genes located on non-homologous chromosomes sort independently of one another during the formation of gametes

Explanation:

Mendel's Law of Segregation states that for a diploid organism, the two alleles of a gene separate during gamete formation, so each gamete only gets one allele.

• Option A describes crossing over, related to genetic recombination, not segregation.
• Option B is incorrect because mitosis produces identical somatic cells, not gametes, so this does not relate to the law.
• Option C aligns with the law: the two alleles of a single gene separate during meiosis, so they will not be in the same gamete.
• Option D describes Mendel's Law of Independent Assortment, not Segregation.

Answer:

C. alleles belonging to the same gene will never end up in the same gamete during meiosis
