June 14, This one-month study plan is specially designed to help you review and retain all the information you need to be prepared for the AP Biology exam. So, ready to tackle a course on the very fabric of life? A few notes before we begin:
Tell where in an organism they are found. Tell how they are produced. A haploid cell is a cell that contains one complete set of chromosomes. Gametes sperm and ova are haploid cells that are produced by meiosis. Diploid cells contain two complete sets an of chromosomes.
Diploid cells reproduce by mitosis making daughter cells that are exact replicas. Some examples are skin, blood, muscle cells also known as somatic cells. In sentences compare and contrast mitosis and meiosis including the steps, purpose and products.
Mitosis and meiosis are types of nuclear division that make different types of cells. Mitosis makes diploid cells that are genetically identical. During meiosis, diploid cells undergo 2 cell divisions that result in 4 haploid cells. Meiosis occurs in sex cells, produces gametes, increases genetic diversity and produces genetically unique cells.
What is gene linkage? Under what circumstances are genes linked?
What makes it ore likely that two genes will be linked in any given process of meiosis? Genetic linkage is the tendency for genes located close together on the same chromosome to be inherited together.
Factors that are likely to cause a gene to be linked is how close together the genes are on the same chromosome. Mendel proposed the law of segregation. Explain why the law by telling what is segregated and when it occurs. W is actually assorting independently?
What test did Mendel do that caused him to propose the law of independent assortment? When a trait does not assort independently we say it is?
The law states that allele pairs separate from one another during gamete formation. Unlinked genes genes located on different chromosomes assort independently because chromosome pairs assort independently during meiosis.
Mendel tested his theory through experiments concerning pea plants. Independently into the newly formed gametes. A did-hybrid cross is what Mendel performed to propose the law of independent assortment. When a trait does not assort independently we say it is a sex-linked gene.
Some genes sort together when they are located on the same chromosome. Write a brief definition and give an example of each of these patterns of inheritance: When one of the alleles is dominant meaning that the gene could be homozygous or heterozygous in order for the dominant trait to be present.
However o must have a homozygous set in order for the recessive trait to be shown. Such as the height of a pea plant Incomplete dominance: When the alleles are heterozygous the trait will be a mixture of both of the traits.
Such as if two flowers are pollinated to create a flower and one of them is white and the other is red then the new flower would be pink. When the alleles are heterozygous the two traits will be equally distributed.
Such as if two chickens mate and one has white feathers and the other has black feathers then the offspring of the two could have a combination of both white and black feathers.
When more than two alleles are inherited from one gene. Such as human blood type. When one trait is control De by multiple genes.Biology AP Focus Review Guide to accompany Mader, Biology AP Edition (Twelfth Edition).
