Modeling Monohybrid Crosses Experiment
1.) 1 trait in involved in a monohybrid cross, meaning that 4 alleles, 2 from each
parent, are involved.
2.) The factor that prevents the expression of a recessive allele is simply that there ar
Mitosis Laboratory Investigation
Objective: What are stages of a cells life cycle and what are the events that take place in
each of these stages
| | | | |
In this lab, we were to observe the stages of the cell cycle, including their growth
and how they divide. We observed cells that undergo mitosis. In this lab, we looked at
cells that were preserved from an onion root tip. We saw different cells that were
In my karyotype, I have discovered that all the chromosomes have bee matched
with their pair, with the exception of one chromosome. This chromosome is chromosome
18. Chromosome 18 on this karyotye does not have a pair; therefore, this karyotype is
In Cell City memorial hospital, the main export, or product to exit the hospital is

make healthy patients. The main office is responsible for instruc
1. Land plants today compare with their ancestors, green algae, in the way that they
both contain chlorophylls a and b, have many caretenoids, store their food as
starch, and both green algae and plants have cell walls made of cellul
In this lab, we experimented with the types of ways that genes can be inherited
when two parents form a baby. We saw everything from complete dominance with
dominant and recessive alleles to a new type of heredity polygenic traits. For complete

Examine the similarities and differences between the structure of cells in animals
and the structure of cells in plants.
