Why Is Lucy Different Than Her Parents
The reason why Lucy looks different than her parents is because when she was getting genetic information from her parents she got different traits from both of them because they are heterozygous which means they are different. So she could either get a dominant trait or a reccesive trait for example if Lucy's mom is dominant for an antena and Lucy's dad is rececive that means the dominant wins so lucys allele would be Aa for antenna which means she would get two antena's

    Because Mary’s phenotype expression is dominant it is possible for Mary to have several variations of genotypes which would possess the dominant allele which could be either homozygous or heterozygous whereas John’s recessive phenotype could only be present through a homozygous recessive genotype. The possible genotypes for Mary would include the homozygous dominant (NN) or a heterozygous (Nn) while John would possess the homozygous recessive (nn). The possible gametes that could be produced by Mary would be N…

    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…

    In the book “Lucy: the beginnings of Humankind” by Donald Johanson the author himself writes his journey of how his friend Tom Gray and himself experienced the most surprising encounter with the oldest fossil of a hominid that they later called Lucy. Donald Johanson and Tom Gray are pale anthropologists and are very well known for their discovery of Lucy. At the beginning of the book the author writes in the first person illustrating how rare it is to find fossils, many who study in this field sometimes have no luck in finding such extraordinary old fossils. Johanson feels “lucky” to have been able to find such fossils that many have been trying to find without any luck. When Johanson and Gray were at a camp in the Afar desert, they went exploring for sediments, fossils, traces that would lead them to a new discovery. They realized that many of the fossils that they were finding on their way had already been found, but luckily before they were about to leave back to the camp Johanson found part of a hominid arm. At first Gray did not wanted to believe Johanson, but then they began to form the puzzle of what it was a hominid.…
