Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth. Human evolution is an outcome of interaction among the following processes:

The Oregon creeping vole, Microtus oregoni, has a very unusual meiosis?. In this rodent, males are XY, while females are XØ (that is, females have only a single X chromosome). During female meiosis, eggs that receive no maternal X chromosome do not mature, so females only produce eggs with exactly one X chromosome. As chromosome content is unchanged from generation to generation, M. oregoni males (who are XY) must deliberately nondisjoin their sex chromosomes. 1a) What types of sperm would M. oregoni have to produce (considering only their sex chromosome content) so that progeny get the right chromosomes? Remember, no inviable combinations are normally produced. 1b) Draw a Punnett square for the sex chromosomes in a M. oregoni mating, with the gametes that are actually produced. Indicate the sex of each offspring. 1c) From which parent do M. oregoni get their X chromosomes? Circle one. Mom Only Random Mom or Dad Dad Only

Given your answers to below problem, is it possible to distinguishbetween the Protenor and Lygaeus mode of sex determinationbased on the outcome of these crosses? Probelm An insect species is discovered in which the heterogametic sex isunknown. An X-linked recessive mutation for reduced wing (rw)is discovered. Contrast the F1 and F2 generations from a crossbetween a female with reduced wings and a male with normalsizedwings when(a) the female is the heterogametic sex.(b) the male is the heterogametic sex.
Temales among these offspring are allowed to freely intermate, producing a flock of F, kittens. Predict The males and the phenotypic ratio for fur color among these many grandkittens. In Drosophila (fruit flies), the wild type eye color, brick red, is actually produced by the deposition of two pigments in the eyes, a dull brown pigment and a brilliant red pigment. These two pigments are produced by the action of two different, non-allelic (and non-linked) genes. Each of these genes has two alleles, a dominant one which causes normal the production of the pigment controlled by the gene, and a recessive one which is defective, and causes none of that pigment to be produced. Thus, a normal eye- color fruit fly must have at least one dominant allele for each of these genes. If a fly is homozygous for the defective, recessive allele of the gene which produces the brown pigment, that fly will have only the brilliant red pigment in its eyes. This condition is called "cinnabar." For this…
Butterflies have an X-Y sex-determination system that is different from that of flies or humans. Female butterflies may be either XY or X0, while butterflies with two or more X chromosomes are males. This photograph shows a tiger swallowtail gynandromorph, which is half male (left side) and half female (right side). Given that the first division of the zygote divides the embryo into the future right and left halves of the butterfly, propose a hypothesis that explains how nondisjunction during the first mitosis might have produced this unusual-looking butterfly. Question is also in the picture.

In Drosophila, the vestigial wings recessive allele,vg, causes the wings to be very small. A geneticistcrossed some true-breeding wild-type males to some vestigial virgin females. The male and female F1 flieswere wild type. He then allowed the F1 flies to matewith one another and found that 1/4 of the male andfemale F2 flies had vestigial wings. He dumped thevestigial F2 flies into a morgue and allowed the wildtype F2 flies to mate and produce an F3 generation.a. Give the genotype and allele frequencies amongthe wild-type F2 flies.b. What will be the frequencies of wild-type andvestigial flies in the F3?c. Assuming the geneticist repeated the selection againstthe vestigial F3 flies (that is, he dumped them in amorgue and allowed the wild-type F3 flies to mate atrandom), what will be the frequency of the wild-typeand mutant alleles in the F4 generation?d. Now the geneticist lets all of the F4 flies mate atrandom (that is, both wild-type and vestigial fliesmate). What will be the…
