How are genes inherited?

Question

I'm doing a presentation on the history of genetics, and I can't find anything. It may sound like a dumb question to ask but if you can answer ASAP!!!

Answer 1

When the cells divide (male gametes and female gametes) certain portions of the DNA are changed (called crossover) and each cell is specific and unique to the characeristics of the parents. This process is called meiosis.

During fertilization, when the cells come together, the chromosome halves also come together forming the full chromosome. Depending on which chromosome half combonations join together from the parents dictates which genetic traits are expressed.

Answer 2

Simply put, genes are inherited through reproduction. An egg and a sperm have genes in them. Pollen and the carpel have genes in them, which combine to form seeds. Each egg and sperm, for example, have half the genes of a full person, and when they combine, the whole is created (23 chromosomes in the egg and sperm, 46 in the human). Humans have chromosomes in pairs (called diploidy), and one chromosome in each pair is from each parent-- 23 pairs of chromosomes=46 individual chromosomes. In that way, for each gene, you have two copies, one in each of the chromosomes. That is how dominant and recessive traits come to be. That is how a parent with brown eyes can have a child with blue eyes. Now I'm getting beyond your question. I hope that helps!

Answer 3

Ugh...
I could write a huge book on that I'll try and condense it as much as possible.
Basically, all cells contain DNA. In a process called meiosis, soon-to-be sex cells divide twice to reduce the amount of DNA by half. When two sex cells fuse, they form a zygote which has the DNA of both parents. The zygote multiplies and becomes the embryo, and then you have a person with half of both parents' DNA.
Try going to www.wikipedia.org and looking up meiosis or genetics perhaps.

Answer 4

gens are inherited throgh chromosomes which have DNA and they DNA have genes on them during reproduction for a human the male and female each give 23 chromesomes which they pair up to give the full 46 chromesomes for a human i hope this enough but you can look it up on wikipedia.com

Answer 5

Okay, I just wrote a blog on this. Write before I saw this question. The blog is descriptive and in normal people words, so don't worry. I hope it is helpful:

Answer 6

This website had none of that medical talk. I could understand it, so I hope it helps.

Answer 7

Go this website. It will explain.
