Mendel's Law of Heredity Flashcards
1
Q
Laws of heredity
A
How traits are passed to offspring.
2
Q
Prevalence of traits
A
This means some traits are more likely to be passed on than others.
3
Q
Alleles
A
Each gene for a trait comes in varieties. Dominant trait is always expressed. Recessive is expressed when both alleles are recessive
4
Q
Genotype
A
Combination of two alleles. Offspring inherit two copies of each gene, one from each parent.
5
Q
Inherited traits
A
Passed from parent to offspring through gametes (egg or sperm) Each gamete carries 1 chromosome of the pair.
6
Q
Human gametes
A
These contain 23 chromosomes. When an egg and sperm fuse together (fertilization) a cell with two copies of each chromosomes (two copies of each gene) results
7

A
Contains 46 chromosomes.
