Alien Genes Projectversion 3

Alien Genes ProjectVersion 3

Today you will find out what your alien looks like, based on it’s parents’ genetics. In order to figure out the exact genotype and phenotype, you will complete a set of Punnett squares that show what your alien looks like. There are several categories, and not all aliens will have the same traits. Describe the parents genotyoes and the alleles before you set up your Punnett squares. You must Draw your alien. Have fun.

You will always select the genotype of your alien (Phenotype is in bold)found in the following square of your Punnett square:

Circle the selected square.

In your alien species:

Both parents are Heterozygous for this trait. Redis Dominant, Orangeis Incomplete Dominant and Blackis Recessive.

Mother FatherColor =

One parent is Homozygous Recessive and one parent is Homozygous Dominant.

Forked toungue is Dominant to not forked.

Mother FatherForked toungue = Yes / No

One parent is Homozygous Recessive, the other parent is Heterozygous.

Tail is Recessive.

Mother FatherTail = Yes / No

One parent is Heterozygous, one is Homozygous Recessive.

No backbone is Recessive.

Mother FatherBackbone = Yes / No

Both parents are Heterozygous. Four eyes is Dominant, Three eyes is Incomplete Dominant and Two eyes is recessive.

Mother FatherNumber Eyes =

Both parents are Heterozygous for this trait.Female is Dominant, Both is Incomplete Dominant and Male is Recessive. (Indicate by hat or clothing color – no external features. Pink is female, Pink and Blue is both, Blue is male).

Mother FatherGender =

Color(s) =

One parent is Heterozygous, the other Homozygous Dominant.

Sharp teeth are Recessive.

Mother FatherSharp teeth = Yes / No

One parent is Homozygous Recessive, the other is Heterozygous.

Wings are Dominant to no wings.

Mother FatherWings = Yes / No

One parents is Homozygous Dominant, the other is Homozygous Recessive. Fivearms is Dominant, Threearms is Incomplete Dominant and Sixarms is Recessive.

Mother FatherNumber Arms =

Both parents are Homozygous Recessive. Fur is Recessive.

Mother FatherFur = Yes / No

Both parents are Homozygous Dominant. No fingernails is Recessive.

Mother FatherFingernails = Yes / No

Objectives: Students will be able to determine alleles of gametes and construct a punnit square. They will use the genotype to determine the phenotype of the alien.

Genetics: 2Mutation and sexual reproduction cause genetic differences in a population.

G2g: how to predict alleles based on the parents genetics.

G3a: how to predict phenotypes in a cross from parental genes, and the type of inheritance (dominant or recessive).
