only dominant genes from a single parent.

|
identical sets of genes from 2 different parents.

|
|
the same number of chromosomes from a male parent and a female parent.

Detailed explanation-1: -When these haploid gametes fuse to form a zygote, the zygote will have 23+23= 46 chromosomes which are equal to the number of chromosomes in the parent cell. Hence both the parents and offspring have the equal number of chromosomes.
Detailed explanation-2: -Answer : Gametes of sexually-reproducing animals have half the number of chromosomes as that of the parents. Thus, during fertilisation, when two gametes i.e. male and female gametes, fuse, the offspring produced will have the same amount of DNA or the same number of chromosomes as that of the parent.
Detailed explanation-3: -Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.
Detailed explanation-4: -Sexual reproduction happens via fertilization. Fertilization is the fusion of gametes from two parents. Fertilization leads to new, diploid offspring. Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring.
Detailed explanation-5: -In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.
