Questions 1
Give an example of a learned trait
Skills- language, sports etc
Acquired physical features- scars, tattoos etc
Give an example of an inherited trait
Things born with- eye colour, hair/fur colour, skin colour, flower colour etc
Reproduction
The process of making new living things (offspring)
false
Which living things can reproduce and pass on traits?
All living things- Plants, animals, and humans
What genes do you need for a dominant trait to show?
At least ONE copy of the dominant gene
Offspring
The young produced by parents
Some traits are inherited and some are learned.
True
Why do children look like their parents?
They inherit genes from their parents
Why do organisms reproduce?
To make sure the species survives
Traits
A feature or characteristic of a living thing
A plant having the same flower colour as the parent plant is an example of inheritance.
True
What letters do we use to show dominant and recessive genes?
Dominant are upper case, recessive are lowercase
What genes do you need for a recessive trait to show?
TWO copies of the recessive gene
Gene
A section of DNA carrying information about a trait
Recessive genes hide dominant genes.
False.
If black fur and a long tail are dominant, and white fur and a short tail are recessive, what will an offspring with these genes look like?
Fur genes: Bb
Tail genes: tt
Black fur and a short tail
If I inherit a dominant brown eye gene (B) from one parent, and a recessive blue eye gene (b) from the other parent, what colour eyes will I have? Genes: Bb
Brown
Inheritance
Passing traits from parents to offspring
If one parent has brown hair (genes BB) and the other parent has blonde hair (bb) there will be a 25% chance the offpring will have blonde hair.
False. Genes are all Bb.
