What have we discussed yesterday? Yes, ____________!

Determining homozygous and heterozygous traits, dominant and recessive traits and genotype and phenotype

That’s right! When do we say that a trait is homozygous?

Yes, ____________!
If the alleles both carry the same trait, they are homozygous,

Very good! How about the heterozygous trait? Yes, ____________!

If the alleles carry opposite traits they are heterozygous.

Brilliant! How about dominant and recessive traits? Yes, ____________!

Dominant traits are the observable traits of an individual while the recessive traits are the ones that are hidden

Excellent! What about the genotype and phenotype? Yes, ____________!

Genotypes are the factors that cause the phenotype which are the observable traits.

    i) The enzyme that would be used to cut the vector would be SalI along with adding the CIP. The main reason that you would cut with the particular enzyme Sal I is because the beginning of the vector sequence there isn’t a stop codon, so but cutting it with Sal I than both the vector and the protein will be compatible. There however is going to be a function of the CIP. CIP is a very important aspect of the whole process because once the vector is opened; the CIP is going to…

    An Analysis of the Observed Heterozygosity of Lake Trout

    This study was undertaken in order to compare the heterozygosity of three Lake Trout populations at various loci. Samples of twenty-five Lake Trout were collected from three lakes: Devil, Eagle and Loughborough, all three of which are situated north of Kingston, Ontario. An autoradiograph was used to analyze the genotypes of the individuals at six different loci of microsatellites, which are repeat sequences in the DNA that are neutral and do not code for proteins. This data was used to compare the genetic diversity of the three different trout populations. Numerical values for observed heterozygosity (Ho) were then generated using the data and the Doh heterozygosity calculator. The results have indicated that the mean heterozygosity in respect of Devil Lake trout was significantly greater than that of the trout in Eagle Lake (p=2.89E-7) as well as that of Loughborough Lake (p=1.44E-19). Furthermore, the mean heterozygosity for Eagle Lake trout was significantly greater than that of Loughborough Lake (p=2.52E-6). This may be due to the fact that natural selection acts as a force to cause inbreeding to eliminate harmful genes causing low heterozygosity in a population. In addition, human and natural effects occurring in the lakes, for example, fishing and water temperature may cause differences in heterozygosity. Understanding and using these findings may help with sustaining fish populations.…

    Chromosomes are threadlike structures made up of DNA and protein, while a gene is a segment of DNA on a chromosome that controls a particular trait. An allele is an alternate form of a trait. Homozygous means that all of the alleles are the same in the DNA, and heterozygous means that the alleles are mixed up. For example, homozygous would be PP or pp, and heterozygous would be Pp. The dominant factor is uppercase, and the recessive trait is lowercase. Gregor Mendel’s legacy theory has been proved by several other scientists as…

    Phenotype is the composite of an organism 's characteristics or traits: such as its morphology, development, biochemical or physiological properties, phrenology, behavior, and products of behavior (Simon, Reece, Dickey, 2010 an organism 's phenotype is a physical description of a certain trait that organism carries. An organism 's genotype depends on which genes that organism inherits from its parents whether it is homozygous dominant gene (AA), homozygous recessive gene (aa), or heterozygous gene (Aa).…

    The distinction between phenotype and genotype is fundamental to the understanding of heredity and development of organism. The genotype of an organism is the class to which that organism belongs as determined by the description of the actual physical material made up of DNA that was passed to the organisms by its parents at the organism’s conception. The phenotype of an organism is the class to which that organism belongs as determined by the description of the physical and behavioral characteristics of the organism. It is essential to distinguish the descriptors of the organism, its genotype and phenotype, from the material objects that are being described.…

    I think that free earlobes is the dominant trait (Because none of the 20 people I surveyed had attached earlobes). I think that no hair on knuckles is the dominant trait (Because 75% of the people I that surveyed had it). I think that straight hair line is the dominant trait ( Because 75% of the people I that surveyed had it). I don't know whether straight hair or curly hair is the dominant trait (Because it was an even split). I think that no cleft chin is the dominant trait (Because 90% of the people I surveyed had it). I don't seem to exhibit any of the recessive traits shown here. I shared the same chin shape, earlobes and amount of hair on knuckles. I didn't exhibit any trait that was not exhibited in my parents. If an offspring exhibited a recessive trait that neither parent exhibited, it would mean that both parents carried it. I was surprised that none of the 20 people had attatched earlobes. Yes, It is possible that a recessive trait…

    Why Do Parents Use Public Humiliation

    Did you think you had strict parents growing up ? Increasingly in America, parents are using public humiliation as a way to discipline out of control teenagers. Moving forward, society needs to decide if this type of discipline is acceptable or not. This particularly topic is very controversy, and has split our country in two. Public Humiliation is not a legitimate use of parental authority because it leads to the teen being harassed & it over uses parental power to acknowledge a point.…
