Sexual reproduction is the production of haploid cells (gametes) and the fusion (fertilization) of two gametes to form a single, unique diploid cell called a zygote. All animals and most plants produce these gametes, or eggs and sperm.
What is the joining of gametes called?
Fertilization. The joining of gametes to form a new organism. Zygote.
What is the union of gametes?
We take the term “union of gametes” to describe the formation of a zygote by fertilization of one gamete by another. We consider the same population of NI female and N, male diploids so that there are ZN, + 2Ns gametes in all.
When two gametes unite they create a?
The process in which two gametes unite is called fertilization . The fertilized cell that results is referred to as a zygote . A zygote is a diploid (or 2N ) cell, which means it contains two copies of each chromosome.
What does not involve the union of gametes?
Apomixis involves the production of seeds without the fusion of gametes.
Do gametes determine gender?
Sperm cells carry either an X or Y sex chromosome. Female gametes, or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX, or female.
