Question

To increase genetic diversity in offspring, homologous pairs ___________ in prophase I, and ____________ in anaphase I.

A) randomly separate; cross over
B) cross over; randomly separate

Answer 1

Answer:

answer is option:B

Explanation:

• Homologous chromosomes inherited from parent- pair along their lengths, gene by gene. Breaks occur along the chromosomes & they rejoin, trading some of their genes

Answer 2

To increase genetic diversity in offspring, homologous pairs 'crossover' in prophase I, and 'randomly separate' in anaphase I.

Option: B

Explanation:

• Sexual reproduction has several infinite possibilities of genetic variations. From this reproduction, the results of off springs are genetically unique.
• When the homologous pair of chromosomes during the prophase I of meiosis occur, then the crossing over will occur.
• Crossing over is defined as exchanging of genetic material between the non – sister chromosomes.
• When the cells are divided during the process of meiosis, then the homologous chromosomes are randomly separated during the anaphase I.
