A code is a species of representation; so, on the received view, genes can be said to represent traits, and genotypes to represent phenotypes. This theory of genetic activity does not imply that genes somehow act alone to produce phenotypic traits. Every biologist knows that development is a ...
Approximately how many genes does the human genome include? What do genes determine? What are some autosomal recessive genetic diseases? What is autosomal dominant x-linked? What are the hallmarks of autosomal recessive traits? What pattern of inheritance does the traits in the pedigrees follow? Is...
This work differs from the "gene for" research of the past because it doesn't rely on the association of a single SNP related to dopamine influencing sensation seeking. Rather, the study looks at a number of SNPs related to dopamine in prior research, to determine if these SNPs work in c...
Do a dihybrid cross Punnett square to determine the possible genotypes of the offspring of an organism with the genotype BBtt and and organism with the genotype bbTt. How many of the offspring have the dominant phenotype for both traits? How many of the...
What genes come from which parent? The chromosomes that determine the sex of the baby (X and Y chromosomes) are called sex chromosomes. Typically, the mother's egg contributes anX chromosome, and the father's sperm provides either an X or a Y chromosome. ...
determine BMI, weight in kilograms was divided by the square of height. All cases of infertility were due to non-obstructive azoospermia (NOA), a condition in which abnormal sperm production results in the absence of sperm at ejaculation. All infertile patients underwent a thorough andrological ...
Secondary sexual traits and associated behaviors can be influenced by environmental factors such as exposure to stressors. Such effects may be mediated by the physiological stress response, which is typified by the release of glucocorticoid hormones. The effects of glucocorticoids on sexual traits such...
Also, the development of genetic testing in order to determine the likelihood of developing certain diseases is also promising. It gives people a choice and allows them a chance to develop a proactive plan against development of the disease. There was story on the news the other day about a...
How many alleles of genes that condition X-linked traits do female and male individuals present?Gene and Allele:Gene is composed of DNA that ensures the expression of a character or trait in an organism. In contrast, the allele is a part of the DNA that will...
How are traits passed from one generation to the next? How do genes determine the traits of an organism? How do control genes differ from other genes? How can characteristic patterns of growth be explained by genetically determined processes? How gene control in a non-inducible system mi...
