In real life, how much do genetics affect personality traits as compared to environment influence? While genes have potential to modify behavior, behavior can also modify genes. How do genes impact this process? How do genes determine the traits of an organism?
How many autosomes and sex chromosomes do gametes have? How many autosomal protein-coding genes does a human have? How are maternal effect genes related to egg polarity genes? How much DNA do humans share with apes? How many autosomal chromosomes are in drosophila?
Question: How much of the gene pool is extinct? Species Extinction: The history of life on Earth is told in the fossil record beneath our feet. However, many fossils abruptly vanish from the record after key dates, indicating that they went extinct because they could no longer adapt to envi...
Two brothers can have different hair color, heights, blood types and so on. Here's why that happens: Instead of a long loop of DNA like our trusty E. coli bacterium, cells of plants and animals have chromosomes that hold the DNA strands. Humans have 23 pairs of chromosomes, for a ...
GCKR: How Genetic Variation Across the Allelic Spectrum Influences Protein Function and Metabolic Traits in HumansGenome-wide association studies (GWAS) have generated considerable interest in glucokinase regulatory protein (GKRP; gene name GCKR) which is an inhibitor of hepatic glucokinase (GCK), an ...
the lab identified a hormone receptor—estrogen receptor alpha (ER-alpha)—that appeared connected to the differences in the sparrows' aggression and parenting behaviors in the wild. The white-striped birds express this receptor at much higher levels than the tan-striped birds, and the more the ...
Fundamental studies have shown that some transcription factors can determine cell fate and that the cell fate is much more plastic than previously considered. While regulation by transcription factors is often regarded as secondary to that by chromatin, the truth is that transcription factors direct ch...
1. Why is it possible for bacterial cells to obtain new genetic traits while humans cannot? 2. Would it ever be possible for human cells to undergo conjugation? Why or why not? Compare and contrast antigenic variation and phase variation ...
Similarly, some animals have a much reduced haploid phase in females compared to males, and this might retard W chromosome degeneration compared to that of Y chromosomes63. Sex chromosome dosage compensation. After recombination has been halted between the sex chromosomes, the non- recombining Y or...
Genes are the basic units that encode for the synthesis of proteins and carry genetic instructions. It's been estimated that the human body has about 20,000 genes. Genes are found inside the chromosomes.Answer and Explanation: The human body is made up of a variety of genes, which have ...
