Question

1. in the table, three of the examples represent reproduction through fertilization. only one represents an incidence of cloning. which of the examples must be that of a cloned offspring? example 1 example 2 example 3 example 4

Explanation:

Cloning involves creating an offspring with the same genetic material as the donor. In Example 3, the egg cell donor has a genotype of RR and the offspring has a genotype of rr, which is not possible through normal fertilization (where offspring get genes from both donors). This indicates an abnormal process (cloning - as it's not following the normal genetic combination from two donors in fertilization). In Example 1, it's a normal combination (R from egg donor 1 and r from donor 2). In Example 2, normal Mendelian inheritance (Rr x Rr can give rr). In Example 4, normal combination (r from egg donor and R from donor 2).

Answer:

Example 3
