first, you set up your 4-by-4 punnett square. Next, you identify your dominant and recessive genes. After that, You simply carry the letters through to their respective quadrants. And match them up like so all right each quadrant will represent a 25% chance that that genotype will result in the offspring. you should end up with something like this.

1. Karyotype- An image of cells in mitosis, which shows the complete diploid set of chromosomes grouped together in pairs
2. Genome EG-full set of genetic information that an organism carries in its DNA
3. Sex chromosome EG-More than 1,200 genes are found on the X chromosome; fewer on a Y chromosome
4. Female chromosome EG-two copies of the X chromosome; XX
5. Male chromosome - one x and one y chromosome
6. Hybridization- crossing dissimilar individuals to bring
   together the best of both organisms
7. Inbreeding- continued breeding of individuals
   with similar characteristics
8. Biotechnology- application of a technological
   process, invention, or method to living organisms
9. Polyploid- have many sets of chromosomes
10. Polyploid- have many sets of chromosomes

A- 2 generations

A-if the gene carriers aren’t affected then it is a recessive trait.

A-because everyone has at least one X chromosome; men only have one X chromosome, so they can only inherit one copy for the trait to show up. Females would need to inherit two copies of it, which is harder.

Q-What is the role of restriction enzymes?
A-Restriction enzymes are able to separate the DNA molecules at a sequence of bases.

Being able to reed a pedigree and fill out a punnet square can help in many professions and normal life. Pedigrees are used to analyze the pattern of inheritance of a particular trait throughout a family. Pedigrees show the presence or absence of a trait as it relates to the relationship among parents, offspring, and siblings.
