Why are there always two alleles present for each gene at a specific locus? 5. True or False. A dominant allele is always written with a capital letter‚ whereas the recessive allele is always written in lower-case. 6. True or False. In a sperm or egg‚ both of the two alleles on the homologous chromosomes are passed on to offspring. 7. When genes are present on the same chromosome‚ they are inherited separately/ together

Today‚ many citizens in America are homosexual; it’s just not an uncommon thing. Since it is becoming less of an issue and more accepted than ever‚ more people are coming out of the closet and wanting to have same sex relationships open ly. Although it is becoming more accepted‚ much of society still does not like the idea of legal gay marriage. As of now‚ very few states recognize legal marriage between gays‚ and it is a problem. In 1968‚ the U.S. government passed an amendment that states; “No

else that comes with being a father. If you look up the word father in a dictionary‚ you will most likely find a definition that is very similar to one of these two: “a man who has begotten a child” (Merriam-Webster) or “a male person whose sperm unites with an egg‚ resulting in the conception of a child” (TheFreeDictionary). According to these definitions‚ any fool who has a child‚ regardless of what he may or may not do to help raise that child‚ is considered to be a father. However a real

States through the use of a process called sperm sorting. Sperm sorting was initially developed as a means to regulate the gender of offspring in cattle. Sperm sorting is achieved through exploitation of the size difference between the X and Y chromosome. The X and Y chromosome are those that will determine the gender of an offspring. The egg of a female contains two X chromosomes‚ and each sperm from the male contains either an X or a Y. If the sperm that inseminates the egg contains a Y

cells and form the organs such as the lungs‚ skin‚ heart‚ sperm‚ eggs‚ and other tissues. An alternate method of harvesting stem cells is from adults. In adult tissues‚ such as brain‚ muscle‚ and bone marrow‚ distinct groups of stem cells generate replacements for cells that die off. This is a good tool for the health field because it creates a possibility for replacement organs and tissues that would normally have to be harvested from live donors. The involvement of stem cells in medicine would increase

In order to create a hypothetical utopian society‚ Aldous Huxley projects the future progression of technology and bases the direction of his novel Brave New World on those predictions. He shows how social standards and beliefs can be changed‚ and how a few upgrades over a few decades can cause society to be nearly unrecognizable‚ vastly dissimilar‚ and frankly quite strange from an outside perspective. Huxley predicts that technological advances can lead to views on birth‚ sex‚ and relationships

Reproduction Male sperm fuses with female egg. If tdf (a gene) is present‚ then the embryo develops testes and produces testosterone. Female Reproductive system • Female baby develops if tdf is not present. • Tdf – a gene located on Y chromosome; if girl‚ then two X chromosomes‚ hence no Tdf. • Female hormones: progesterone and estrogen ( both secreted by mother’s ovaries and placenta which allow female genetilia to develop. Parts of the female reproductive system:

Fertilization in Humans Fertilization begins with the fusion of two haploid cells into a diploid cell‚ the two haploid cells being a sperm cell and an egg cell into the diploid cell being zygote. The union can either be an external fertilization or an internal fertilization. This essay will focus on the internal fertilization found in mammals‚ and more specific‚ in humans. The first part will consider human anatomy of both the female and male sexual reproductive systems‚ and then follows a
