This is a picture of a karyotype. This is a male because there is a y chromosome. Geneticists use these to identify, organiz e, and study human chromosomes. The chromosomes all pair up to form chromosome pairs. Each chromosome has code for a different phenotype.

Unit summary
In this unit we learned about Mendel's law, punnet squares, and pedigrees. Mendels law is the of segregation that says, "organisms inherit 2 copies of each gene one from each parent." The offspring can receive a dominant or recessive allele. Homozygous has 2 same alleles and heterozygous and different alleles. Genotype is the makeup of a gene while phenotype is the physical characteristics. Punnett squares can predict the genotype of offspring. There are different types of Punnett squares including a dihybrid cross has more than 2 alleles. Pedigrees are like a family tree. Circles represent women and squares represent men. A colored in square means they have the recessive gene while half colored in means a carrier. I liked learning about punnett squares because I could predict the offspring. I would like to learn more about codominace and incomplete dominance.
