Answer:

What are the similarities between the reproductive system of humans and animals?

All reproduction is basically the division of a cell into more cells.

Humans ARE animals so the same system applies to all these organisms.

Each individual starts as a single cell - an ovum - with a full set of the species' chromosomes/DNA - in humans always 22 and an X.

Animal species such as cats and dogs have their own set, unique to their species, with the ovum always found in the female body, stored in the ovary.

It will divide into a new cell but it has to go through the body stage to do this. The ovum can make a body if it receives a second matching set of chromosomes to double its set for body cells.

A sperm (made and delivered by the male body) brings this second matching set (fertilization) and the ovum - now called the zygote because it has a double set - divides (by mitosis) into millions of double-set body cells, which clump into organs to do the work for the first cell- we call this a body.

Soon after the embryo is complete (now a foetus) millions of new ova are made by oocyte cells.

They have the double set reduced to the correct single set by a special form of division (meiosis) After birth the body will grow and mature and the fertilization event will occur again

Answer 2

Answer:

Animal Models and Human Reproduction presents a comprehensive reference that reflects the latest scientific research being done in human reproductive biology utilizing domestic animal models. Chapters on canine, equine, cow, pig, frog, and mouse models of reproduction reflect frontier research in placental biology, ovarian function and fertility, non-coding RNAs in gametogenesis, oocyte and embryo metabolism, fertilization, cryopreservation, signal transduction pathways, chromatin dynamics, epigenetics, reproductive aging, and inflammation. Chapters on non-human primate models also highlight recent advancements into such issues as human in vitro fertilization (IVF) and assisted reproductive technologies (ART).
