Zainab is in science class, and he is studying an organism that reproduces sexually. the genetic material of the organism a. will be passed to its offspring without any changes. b. is a blend of the genetic material of its parents. c. is identical to its parents' genetic material. d. all of these

answer: b. is a blend of the genetic material of its parents 

sexual reproduction  is where two  distinct types of reproductive  cells  called  gametes  fuse together. they are known as egg or a female's large  ovum and a male's sperm. each gamete contains half the number of genetic materials or chromosomes  of the organism. the two gametes fuse and their genetic material of parents blend during  fertilization to produce  dna replication  and the creation of a single-celled  zygote  which now includes genetic material from both gametes. the process of blending of genetic material of parents is called genetic recombination. 

since there are no options posted i'll give you a few examples.
