The number of possibilities that can be sampled in the average life span of a female. Concept introduction: Human contains 23 dissimilar chromosomes. By excluding the chromosome cross-over, a human can produce 2 23 =8.4 X 10 6 genetically dissimilar gametes. Crossing over involves the exchange of genetic material between two homologous chromosomes that take place during the pachytene stage of meiosis I. This crossing over can produce variation. Hence, meiosis can occur by ignoring the effects of crossing over.

(A)

Summary Introduction

To explain: The number of possibilities that can be sampled in the average life span of a female.

Concept introduction: Human contains 23 dissimilar chromosomes. By excluding the chromosome cross-over, a human can produce 2²³=8.4 X 10⁶ genetically dissimilar gametes. Crossing over involves the exchange of genetic material between two homologous chromosomes that take place during the pachytene stage of meiosis I. This crossing over can produce variation. Hence, meiosis can occur by ignoring the effects of crossing over.
