Question

Which events in meiosis are responsible for the principle of segregation? select all that apply

Answer 1

Separation of homologous chromosomes in anaphase 1 is responsible for the principle of segregation.

• Mendel put out the law of segregation after noticing that true-breeding pea plants with opposing features produced F1 generations that all displayed the dominant trait and F2 generations that expressed the dominant and recessive traits in a 3:1 ratio.
• According to the law of segregation, each diploid individual has two alleles (copies) for a specific attribute.
• During meiosis, the two different alleles for a single gene segregate as the chromosomes divide into several gametes, resulting in each gamete acquiring one of the two alleles.
• The fundamental tenet of the rule is that copies of genes separate or segregate, resulting in just one allele being passed on to each gamete.
• Hence in anaphase 1 when the homologous chromosomes are pulled apart the alleles also segregate.
