It’s A Baby! Using Genetics to Identify Traits Model

(this is a modeling tool- the traits are not really found on these chromosomes)

Chromosome #7 contains the genetic code for hair type. The "W" hair-making DNA codes for

amino acids which contain a sulfur atom which causes cross links

between amino acids in the hair... thus curly hair! Straight hair lacks the

many sulfur amino acids and does not make as many cross links. Place

your baby's genotype for hair type in the data table.

Chromosome #8 contains the genetic code for Widow's Peak. If

your baby has a dominant "P" then he or she will possess that trait.

(Notice that there is a line through the recessive small “p".) Place

your baby's genotype for Widow's Peak in the data table.

Chromosome #9 carries a gene for eyebrow thickness

called "T". It works with complete dominance. Place your

baby's genotype for eyebrows in the data table.

Chromosome #10 has the gene for eyebrow placement. "E"

separates and lack of "E" causes connected eyebrows

Place

your baby's genotype for eyebrow placement in the data table.

Chromosome #11 has the gene for eye

placement. The dominant gene places the eyes

close together, the recessive, far apart. Place your

"baby's" genotype for eye placement in the data table.

Chromosome #12, besides carrying one of the pigment

genes for eye color, also carries the gene "I" for eye

size. Place your "baby's" genotype for eye size in the data table.

Chromosome #13 has the eye shape gene "V." Dominant genes

code for almond shape and homozygous recessive is round. Place

your baby's genotype for eye shape in the data table.

Movie star eyelashes are found on chromosome #15. Dominant "M"

genes place your kid on the way to stardom! Place your baby's genotype

for eyelashes in the data table.
