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 #17's "Q" gene controls the width of the

mouth. The dominant gene imparts width. Place your

baby's genotype for mouth width in the data table.

Chromosome #18's gene "J" adjusts the thickness of the

lips. Place your baby's genotype for fullness of lips in the

data table.

Chromosome #16 contains genetic information regarding the

construction of dimples. Place your baby's genotype for dimples in

the data table.

Chromosome #19 contains genetic information regarding the

construction of nose size. Place your baby's genotype for nose

size in the data table.

Your baby's nose shape is determined by a gene on chromosome #14.

The allele "U" imparts a rounded shape to the nose. Place your baby's

genotype for nose shape in the data table.

Chromosome #22 carries the gene for free ears. The gene "Z" causes the

earlobe to hang free at the side of the head. Place your baby's genotype for

earlobe attachment in the data table.

Chromosome #20 contains DNA information encoded in a gene called "D" for

ear hair. This information, if in its dominant form, causes the ear to grow a large

amount of fuzzy hair. Place your baby's genotype for hairy ears in the data table.

Chromosome #21 contains a gene, "$" which causes uneven pigment to form in the cheek region.

If "$" is present then your child will have cheek freckles. Place your baby's genotype for freckles

in the data table.

All information is compiled from the following sight:
