Life Science Chapter 5 - Song Lyrics                                       

 

Sex Cells (23+23)

 

The passing of traits

from parents to offspring is heredity.

Two “X” chromosomes make

a girl and an “X” and “Y” is gonna be

a boy.

 

Parents pass their traits

through genes and their alleles to the child

the pairing of these alleles makes

the offspring’s genotype.

 

Cells have twenty three pairs of chromosomes,

mostly made of DNA.

Sex cells are the only exception

cos these have half as many -

an egg needs a sperm’s chromosomes to be complete.

 

Dominant traits

are displayed in the next generation.

Recessive traits,

may show up with the right combination.

 

Parents pass their traits

through genes and their alleles to the child

an organism’s outward display

of its genes is called its phenotype.

 

Cells have twenty three pairs of chromosomes,

mostly made of DNA.

Sex cells are the only exception

cos these have half as many -

a sperm needs an egg’s chromosomes to be complete

yes, to conceive, they need twenty three plus twenty three.

 

Two alleles for each gene

and genes are found in chromosomes

most cells have 46 of these

but sex cells have half as many!

 

Cells have twenty three pairs of chromosomes,

mostly made of DNA.

Sex cells are the only exception

cos these have half as many -

an egg needs a sperm’s chromosomes to be complete

yeah, to conceive, they need twenty three plus twenty three

yes, a sperm needs an egg’s chromosomes to be complete.
