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.
