MAKING BABIES

Click here to return to Web View

We will be making babies today --- on paper of course! In order to do that you will have to donate a gamete to the sperm/egg bank. Before any donations are made, you have to determine some things about your own genotypes and phenotypes.

Procedure:

  1. Determine your personal phenotype, then genotype, by following the cahrt below and filling in TABLE 1 on the back of this page.

Master Chart

1. Face Shape/ RR=round Rr=round rr=square

10. Eyelashes/ LL=Iong Ll=long ll=short

2. Skin Color / See Fact Sheet

11. Lip thickness/ TT=thick Tt=medium tt--thin

3. Hair Type/ CC=curly Cc=wavy cc=straight

12. Cheek Dimples/ DD=present Dd=present dd=absent

4. Widow's Peak / WW or Ww=widow's peak ww=no widow's peak

13. Nose Size / QQ=large Qq=medium qq=small

5. Eyebrow Thickness/ BB=bushy Bb=bushy bb=fine

14. Nostril Flair Shape/ GG or Gg = rounded, gg = pointed

6. Eyebrows / NN=unconnect Nn=unconnect nn=connected

15. Ear Lobe Attachment/ FF or Ff=free, ff=attached

7. Eye Color / See Fact Sheet

16. Ear Hair/ HH or Hh=no hair,hh=hairy

8. Eye Separation/ EE=wide Ee=normal ee=narrow

17. Cheek Freckles/ ZZ=present Zz=present zz=absent

9. Eye Angle/ HH or Hh=horizontal, hh=upward

18. Forehead Freckles/ YY or Yy=yes, yy=no

NOTE: For men, you will only have a Y or y for #18, Forehead Freckles

  1. Now that you have written down your own phenotype and genotype (on Table 1), you must write down the letter of each allele on teh appropriate chromosomes in your karyotype. Be sure to place the alleles at the site of the gene. Make sure your capital letters are tall, and your lower case letters are short!!!!

  2. It's almost time for your gamete donation. First we must undergo a round of meiosis. You will cut out your chrmosomes and place one of eachpair into plastic bags representing your gamets. When you are finished, choose a secret code and write it on the outside of yoru bag. You keep one gamete and donate one to the sperm ban or the egg bank.

  3. Fertilization Time!! You will be given a donated egg or sperm. Combine it with the gamete you kept. This represents fertilization. Next you will arrange the chromosomes based on size and glue them onto paper to create the karyotype of your baby. Record the genotype and phenotype of your baby on TABLE 2.

  4. Finally! Fill out the birth announcement of your baby and draw an accurate (use the fact sheet) and colorful picture of your child at the age of 15! All parts of the baby packet will be turned in. This includes the karyotype of your baby.
