DNA contain many genes. and with 2 different parents with many different genes and traits of their own, the number of possible combination is enormous

In sexual reproduction an offspring is produced with genes from both parents. When the offspring has a new genetic variation that it got from neither of its parents it is called?
mutation
What structures carry genes to the offspring?
According to the chromosome theory of inheritance, genes are carried from parent to their offspring on chromosomes.
What is carried from parent to offspring on chromosomes?
Chromosomes carry genes from parent to offspring. A gene is a section of DNA which carries coding for particular protein.
When does genetic variation occur?
It happnes when genes are being passed down from the parent to the offspring and environmental differences alter the genes being passed down
What are the chromosomes that carry genes that determine your gender?
Genetic chromosomes

How does meiosis introduce genetic variation in to offspring?
Meiosis produces gametes which then go on to participate in sexual reproduction. Sexual reproduction combines the genetic material of the two parents - therefore creating variation.
What structures carry genes to the offspring?
According to the chromosome theory of inheritance, genes are carried from parent to their offspring on chromosomes.
What is carried from parent to offspring on chromosomes?
Chromosomes carry genes from parent to offspring. A gene is a section of DNA which carries coding for particular protein.
Which cell division mitosis or meiosis has genetic variation and are not just identical cells?
Meiosis. Genetic variation is achieved by the random division of the chromosomes between the two daughter cells, and further recombination of specific genes between paired chromosomes before the division.
When does genetic variation occur?
It happnes when genes are being passed down from the parent to the offspring and environmental differences alter the genes being passed down
Difference between chromosomes and genes?
Chromosomes carry genes. Genes are inherited material that is in chromosomes. Traits are determined by the genetic information found on chromosomes.
What are the chromosomes that carry genes that determine your gender?
Genetic chromosomes
What carries genes from parents to offspring?
The chromosomes are the ones that carry genes from parents to offspring. This is done through meiosis where sex cells are produced.
What role do chromosomes and genes play in determining a child's heredity?
Genes are the basic unit of genetic inheritance. Chromosomes are the structures inside cells that contain the entire genome. Naturally, genes and the chromosomes that contain them, and how genes arrange themselves on the daughter chromosomes during meiosis are critical to the process of determining the heredity of the offspring.
Asexual reproduction increases genetic variation-the raw material on which natural selection operates?
Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
