Genetics Answers

1. Hypothetically, you are given the chance to enhance/modify a trait of certain

plant/crop. These are the things that you will consider to make a genetically modified

organism (GMO)

a. Identify special trait.

b. Identify a source organism

e. What benefit/s would the recombinant organism provide to society?

In summer squash, white fruit color (A) is dominant over yellow fruit color (a). If a squash plant

homozygous for white is crossed with a plant homozygous for yellow, what will the phenotypic and

genotypic ratios be for:

Where the two alternatives for a trait are broad and narrow, and broad is dominant, the phenotype of a homozygous dominant individual would be expressed as

alleles of genes are present on ?
