Due to mendel's 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

The correct answer is C) Alleles belonging to the same gene will never end up in the same gamete during meiosis.

According to the Mendel's law of segregation, during the process of gamete formation in meiosis, the alleles ( different forms of a gene) are separated from one another so that every gamete receives one allele.

This is also called law of purity of gamete as alleles never end up in the same gamete during meiosis.

Thus, option C) is the right answer.

the correct answer is 2 and 4
