1. Imagine that nose size is a phenotype expression of the gene N. Let’s agree that large nose size (N) is dominant and small nose size is recessive (n). John has a small nose and Mary has a large nose.…
| One specific form of a gene (differing form other alleles by one or few bases, occupying the same gene locus as other alleles of that gene)…
T 6. It is entirely likely for a gene to have more than two alleles.…
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…
1. In fruit flies, long wings are dominant to short wings. Complete a cross between a short winged male and a heterozygous female.…
* There has been a major effort in the history of science to figure out the structure of DNA. Having a double standard helix DNA has a uniform a diameter in its entire length. The helixes fit within a defined three dimensional space because they are both right handed. Polynucleotide chains are held together by the bases in the (center) hydrogen bonding with the bases on the opposite polynucleotide. Two polynucleotides are form around the outside of the helix with the bases extending into the center. Known as complementary base pairing; hydrogen bonding is a very specific process. Scientist had identified all the atoms and knew how they were bound together. What was not understood was the capacity to store genetic information, copy it and pass it from generation to generation, and the specific three dimensional arrangements of atoms that gave DNA its unique proprieties.…
The genotype is the genetic makeup of a cell, an organism, or an individual, Where as a…
A: You could have many different colors made through different allelels put together, Colors are also x linked, while the others are autosomal.…
c. In week 2 we discussed that individuals can have no more than two different alleles for each trait. In population genetics we can operate with multiple alleles for each trait. How is it possible?…
What is an allele? How many alleles make up one gene? Alleles are alternative forms of a factor. Two alleles make up one gene.…
Genes are found in our chromosomes,which parents pass on to offspring in their sex cells in reproduction. Different versions of the same gene are called alleles, and these can determine features like eye colour, and the inheritance of disorders such as cystic fibrosis.…
(1)______Allele_____ - genes (Gene - segment of DNA that codes for single protein) coding for the same traits on each pair of homologous chromosomes. The alleles may be identical or different.…
Genotype is the allele constitution in an individual for a particular gene. Phenotype is the physical expression of an allele combination.…
Examples of Genetic Characteristics by Erik Bank says that when you have a short glance in the mirror it will reveal a number of genetic traits which there is one allele that dominates over the other. Oval-shaped face, widow peak, long eyelashes, dimples and freckles are the dominant trait that can be observed through facial features. There are also recessive trait that can be observed like for example square face, short eyelashes, a slender eyebrow, a cleft chain, straight hairline and attached earlobe. He assort that long eyelashes is a dominant…
In humans, there are chromosomes that determine sex and there are genes that determine the color of your eyes. Generically speaking, there are X & Y chromosomes that determine whether you are either male or female suggesting that you either are a female or are not a female. With genes, there are dominant genes and recessive genes, suggesting that while you might carry a gene for blue eyes, you may also have a dominant gene from brown eyes which would win out to determine what your eye color is.…
