Quick Answer: What process produces diploid zygote?

Does meiosis produces a diploid zygote?

In sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote (Figure 1 and Figure 3). Figure 1: Fertilization of an egg cell by a sperm cell. In sexual reproduction, haploid gametes fuse to produce a diploid zygote.

What is the process in most animals that produces diploid zygotes?

Chapter 7-Meiosis and Sexual Reproduction

A B
fertilization the process in most animals that produces diploid zygotes
clone an individual produced by asexual reproduction; genetically identical to parent
asexual the kind of reproduction in which a single parent passes copies of all its genes to its offspring

How is a diploid zygote produced?

When egg and sperm cells combine in fertilisation, they merge the two sets of chromosomes, ending up with 46 chromosomes in total. … The resultant cell is called a zygote. It is diploid as it has two copies of every chromosome – one came from the sperm cell and one came from the egg cell.

How is a diploid zygote formed?

Diploid zygote is formed by the fusion of male and female gametes. … Hint: The fusion of haploid gametes, egg, and sperm to form the diploid zygote is fertilization. Fertilization restores the chromosome number. The offspring are produced by the growth of the fusion product of gametes called a zygote.

Is zygote produced by mitosis?

Animals spend most of their life in the diploid genetic state, and only undergo meiosis at the time of gamete production. … Two haploid gametes fuse (fertilization) to produce a diploid zygote, which divides by mitosis to produce the large number of diploid somatic cells in the animal body.

What is a diploid life cycle?

Organisms with a diploid life cycle spend the majority of their lives as diploid adults. When they are ready to reproduce, they undergo meiosis and produce haploid gametes. Gametes then unite in fertilization and form a diploid zygote, which immediately enters G1 of the cell cycle. Next, the zygote’s DNA is replicated.

Which event leads to diploid cell in a life cycle?

A diploid cell is the product formed when two haploid cell fuse together. The chromosomes inside a diploid cell are contributed by one set of chromosomes of both the parents. Meiosis is a cell cycle process where a cell undergoes two nuclear divisions to form four haploid cells.
