Answer:

Meiosis → Sex cells→ Fertilization → Zygote

Explanation:

Answer:

(4). meiosis → sex cells → fertilization → zygote.

Explanation:

Sexual reproduction can be defined as a type of reproduction, in which new living organisms are produced by fusion of gametes produced by two organisms of different sexes.

The first step in sexual reproduction is meiosis that involves formation of haploid gametes (eggs in females and sperms in male) from diploid gamete-forming mother cells.

In next step, the male gamete (sperm) and female gamete (egg) fuse together, which is known as fertilization. Fertilization leads to development of a single-celled, diploid zygote. Later on, the zygote divides and differentiates into multicellular diploid organism.

Thus, the correct answer is option (4).

The bicoid (bcd) gene in Drosophila melanogaster has a role in establishing the polarity of the insect larva early in developmen
nikklg [1K]

Answer and Explanation:

A maternal impact quality is a quality the incipient organism doesn't express, rather, it is a quality the mother communicates, that by one way or another has an effect on the improvement of the hatchling. Models incorporate qualities that decide extremity of the incipient organism, and qualities that decide the body plan of the developing life, for example, bicoid in Drosophila, which decides head and thorax position.

The bicoid quality figures out which end is the front finish of the fetus. A homozygous transformed bicoid quality outcomes in the absence of foremost fragments, for example, mouth parts, head, and the initial two thoracic portions. It additionally brings about a hatchling creating two back closures (thus the name bicoid).

The phenotype of the hatchlings will be typical, since the mother is ordinary, and it is a maternal impact quality.

The descendants would be transformed as depicted above
