I need help with dominant and recessive genes, it doesn't really make sense to me ​can sombody explain how it works?

Dominant: the genes that are expressed/ shown

Recessive: the "hidden" genes

Explanation:

If one parent has a dominant gene for brown eyes and the other has a recessive gene for blue eyes, then the offspring will have brown eyes.

Hope this helps!

You can message me if you are still confused.

Explanation:

dominant genes will always appear before recessive ones, in order for recessive genes to appear, both copies of the gene have to be the recessive one tldr for this paragraph, think of dominant genes like jackets, and recessive ones like t shirts

an example

B=brown hair gene (dominant)

b=blond hair gene (recessive)

this is an example of 2 parents, with offspring

Bb Bb <-- both parents have a copy of brown and blond hair gene, but since dominant genes appear before recessive ones, they both have brown hair

now, lets look at their possible offspring genes

BB Bb Bb bb

in order, their hair color will be

brown, brown, brown, blond

see the last one? the only reason why that child is blond is because they don't have a brown hair gene tldr of this paragraph, recessive genes will only be present if both copies of the gene is the same

with the first example, lets say its a cold day. what would you wear, a jacket or a t shirt? a jacket, obviously

but what if you only had t shirts? then you would be forced to wear that and think about your poor freezing self...

pretend the T shirt is blond hair gene, and jacket is brown hair

and the closet only holds 2 clothes

2 domiant genes will do the same thing, brown hair

1 domiant gene and 1 recessive will use the domiant gene, since domiant genes get used first, like brown hair will show even though you have a copy of blond hair gene

2 recessive genes, and only then will the recessive show, like blond hair

uwu wow this took way too long to type
