In this session, i had to learn some basics and definitions in genetics. Chromosomes was one of m words that i had to learn. Every human has 23 pairs of chromosomes in their body. I also had to construct a model of a DNA molecule and explore a history of the science of genetics.
In this session, i had to explore the process of mitosis and explore the process of meiosis. Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
In this session, i had to investigate how dominant and recessive genes combine. In genetics, a trait that will appear in the offspring if one of the parents contributes it. For example, dark hair is a dominant trait. I also had to simulate the generation of offspring from different parent genotypes and determine genetic notation.
In this session, i had to use LEGO bricks to simulate alleles. I also had to combine alleles to produce offspring. A green lego is dominant over red and yellow. The theoretical probability refers to the likelihood that something will happen without doing any experimentation.
In session 5, i learned about sex-linked traits and i had to analyze genotypes and phenotypes of a dihybrid cross. A sex-linked gene are genes located on the sex chromosomes, typically the X chromosome. A sex-linked trait are the traits that are expressed by these genes.
In session 6, i had to discuss the risks and benefits of genetic research. I also learned about ways that genetic research is used in modern society. Genes can be isolated and then inserted into an offspring. Cutting and passing genes is known as genetic engineering.
In session 7, I used LEGO bricks to simulate a population. I also explored the effects of natural selection on a population. Genetics also spend a large amount of time gathering data about a population so they can establish trends within the population.
