Having gene versions that are the same
Homozygous
The instructions for making a protein are called ____.
Genes
A specific form of a gene
Gene Version or Allele
Looking at the image are these chromosomes homozygous or heterozygous?
heterozygous
3rd
A type of gene version that is located on the chromosome.
Allele
What cell organelle (part) is response for using instructions from genes to MAKE the proteins
Ribosomes
True or False: Organisms CANNOT have different proteins in their cells for a particular feature
False
Leo has medium silk flexibility and a gene combination of F1F2 his mate Ruby also has medium silk flexibility and a gene combination of F1F2.
Will all of their offspring have medium silk flexibility? Explain.
In a Punnett square, which allele (gene version) is shown with a lower-case letter?
Recessive allele (gene version)
A specific characteristic of an individual organism
Trait
The function of a protein molecule depends on its ____ and how it interacts with other proteins
Structure
This silk flexibility trait is best for using as tendon replacements and stitches.
Medium Silk Flexibility
Leo and Ruby are both heterozygous for silk flexibility (F1F2). What are the THREE possible gene combinations for their offspring?
F1F1, F1F2, F2F2
In the Punnett square below, the gene version B represents brown eyes and the gene version b represents blue eyes. What percent of offspring will have BLUE eyes?
0%, even though two of the genotypes (Bb) contain one recessive gene version for blue eyes (b), the dominant brown eye gene (B) will overpower and be the trait.
Having gene versions that are different
Heterozygous
Two spiders have different parents. One spider is brown in color, and the other spider is yellow in color.
Why are the spiders different colors?
The spiders have different versions of the gene for color, which instruct for different proteins that connect in different ways to make different colors.

A. V1V3
B. V2V3
C. V3V3
Explain
C. V3V3
