Regeneration, the regrowth of lost body parts, normally follows
a) all types of asexual reproduction. b) all types of sexual reproduction. c) fission. d) fragmentation. e) parthenogenesis.

Answer; fragmentation

Explanation:

Most animals reproduce by fragmentation. This is a type of asexual reproduction.

In fragmentation, parts of their bodies divides and forms new organisms. Animals that undergo fragmentation as a type of reproduction have high regeneration power.

Regeneration occurs by mitosis division where the daughter cell formed has the same number of chromosomes as the parent cell.

As the cell continues to divide through mitosis,the animal gradually becomes a whole organism.

An example of such animals is sponge (porifera).

"do a testcross with a homozygous recessive plant."

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
