Does half of the genetic code come from the female gamete and half from the male?

in short, yes.
the gen. code is split over chromosomes, which come in pairs. a human has 23 such pairs.
one of from each pair comes from the father and one from the mother.
each chromosome itself consists of two strains, with one being the mirror of the other.
this is a rather complex topic, for a more detailed answer, see wikipedia. (hets half of its genetic code from the father and half from the mother)

Does cossing over lead to genetic variation?
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
What are the Social issues relating genetic engineering?
there are many issues dealing with genetic engineering, most people who go through genetic therapy come out with a disease, when they didn't before
Where does source code come from in java?
Source code comes from the programmer...
What causes genetic variation in a species?
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
What does the term genetic engineering refer to?
From the Web site of safe-food.org, genetic engineering is "a laboratory technique used by scientists to change the DNA of living organisms." Put another way, genetic engineering is "the alteration of genetic code using artificial means" (from www.globalchange.com). Genetic engineering is also called bio-engineering, gene-splicing, gene manipulation, etc. and the organisms that result from the practice are called genetically modified organisms (GMOs).
What comes from the female parent?
It's called an Egg. or an ovum, a female gamete
What is a gamete machine?
This is a slightly metaphorical term because gametes are created by organs, not by machines, but since the organs that create gametes do so in a relentless, almost mechanical manner, we might call them gamete machines. Collectively, the organs that create gametes are called gonads. These come in two varieties, the male gonads, known as testes, which produce the male gamete known as sperm, and the female gonads known as ovaries, which produce the female gamete known as eggs or ova.
does the sperm cell come from male or female?
Gametes come from both the mother and the father. The mother's gamete is known as an egg and the father's gamete is known as a sperm.
What is a gamete In terms of the number of alleles for each gene what general statement can you make about how gametes differ from other cells in a mature pea plant?
Gametes come in two forms, sperm (the 'male' gamete) and eggs (the 'female' gamete). Each of these gametes only contain half the number of chromosomes that the main organism's cells have, because these cells combine both male and female to create new organisms.
What is another name for sex cells?
Another word for sex cells is gametes. A male and female gamete come together to form a zygote: the first cell of the new organism.
Process where male and female sex cell join is called?
In the sexual reproduction of plants, the male and female gametes join to form a single fertilized cell called a zygote. This zygote then develops into a new individual plant with a unique collection of genetic material. Many flowering plants are also able to reproduce asexually through structures such as stolons, rhizomes and tubers.
How many chromosomes come from the mom in a gamete?
Pretty sure its 23
Do humans reproduce asexual or sexual reproduction?
Sexual reproduction is reproduction involving the union or fusion of a male and a female gamete. These gametes must come from two organisms, a male and a female. Asexual reproduction is reproduction through cloning or budding. Humans reproduce sexually.
How much genetic information is present in the sperm and egg?
The egg contains the genetic material of the female The sperm contains the genetic information of the male Once the egg is fertilised it contains the genetic information of both parents - male and female.
What effects does union of haploids in fertilization have on genetic diversity?
Fertilization is random and the haploids are male and female gametes, sperm and eggs. So, genetic diversity is enhanced greatly because random fertilization comes after the independent orientation of male and female chromosomes plus crossing over in meiosis. So, statistically speaking, there are myriad variations that can come out of haploid random fertilization and so great genetic diversity is also enhanced here.
