Question4 0.5 pts Genetic recombination is a feature of sexual reproduction. Which of the following contribute to genetic variation in each generation thanks specifically to sexual reproduction (ie. would not also be true of asexual reproduction). (Select all the apply). DNA exchange between homologous chromosomes during prophase random orientation of chromosomes during meiotic metaphase random fusion of gametes during fertilization mutation generated by mistakes during DNA replication ? random orientation of chromosomes during mitotic metaphase

Explanation / Answer

1. DNA exchange between homologous chromosomes during prophase.

2. Random orientation of chromosomes during meiotic Metaphase.

During prophase , crossing over occurs between non sister chromatids of homologous chromosomes in 2hich nonsister chromatids exchange parts. Due to this process there is produced new combination of genes as paternal and maternal genes are exchanged.

During Metaphase chromosomes orient independently of each other which also produces variations.
