Answer:
Sunlight, humidity, soil type, temperature
Dr. Evil has just discovered a way to prevent mating from occurring during meiosis in the gametes of his lab rats. the effects her discovery would have on laboratory mice is that prophase I would be interrupted and there would be reduced genetic variation in the offspring of the mice. because crossover occurs during prophase I of meiosis I and results in genetic recombination, which promotes genetic variation. If this is avoided, genetic variation would be significantly reduced in the offspring.
<h3>What happens in prophase 1?</h3>
Prophase I – in this stage, the condensation of the chromosomes occurs; the temporary disappearance of the carioteca; disappearance of the nucleolus and the duplication of centrioles to the poles of the cell. In prophase, the exchange of genes (crossing-over) also takes place, through the exchange of pieces between homologous chromosomes.
With this information, we can conclude that Prophase I is the first stage of meiosis I. In it, the pairing of homologous chromosomes occurs and a phenomenon known as crossing-over can occur.
