Why are phenotypes the product of both their genes and their environments?
How is it possible for humans to differ genetically from each other if we all have the
same genes arranged in the same order on our chromosomes?
As pointed out in the section Evolution of the Y Chromosome, some researchers have predicted that the human Y chromosome will continue to lose genetic information in the future and will completely disappear from the species in about 10 million years. What would happen if the Y chromosome disappeared from the human species?

- How does the diploid condition protect harmful recessive alleles from natural selection?arrow_forwardIn mammals, more than one chiasma per chromosome arm is an indication that crossing-over has occurred. Scientists compared the average number of chiasma among the species shown in the table. Based on the data, which of the following questions could be asked to determine how the genetic diversity of these mammals would be affected in future generations? A - Are baboons or dogs more genetically diverse? B - Are horses more genetically diverse than other mammals? C - Are baboons less genetically diverse than other mammals? D - Do horses and cats express a comparable amount of genetic variation?arrow_forwardYou are an allele on a single uncondensed chromosome in a Yellowfever-carrying mosquito (Aedes aegypti) diploid cell (2n = 6). Demonstrate in as much detail as possible (1) how you will get to each genetically identical diploid cell of the multicellular offspring; (2) how you will get to the next generation of sexually reproduced progeny. Help, I no understand. Perhaps you will?arrow_forward
- One of the earliest postzygotic barriers to arise is hybrid sterility. Two plants can be crossed, but the resulting seeds grow into sterile plants that cannot reproduce. Is this as important in plants as it is in animals (Hint: How many types of hybrid flowers and fruits are there, compared to hybrid animals)?arrow_forwardWhat is the generation of allele combinations through genetic exchange between homologous chromosomes?arrow_forwardWhat is the genomic conflict hypothesis for the origin of genomic imprinting?arrow_forward
- The duck-billed platypus has a unique mechanism of sex determination: females have five pairs of X chromosomes (X1X1X2X2X3X3X4X4X5X5) and males have five pairs of X and Y chromosomes (X1Y1X2Y2X3Y3X4Y4X5Y5). Do you think each of the X and Y chromosome pairs in males assorts independently of other X and Y pairs during meiosis? Why or why not?arrow_forwardWhat is genetic drift?arrow_forwardHow many different types of gametes with respect to the R and B genes can an individual with the genotype: Rr bb produce?arrow_forward
- What is pleiotropy in biology?arrow_forwardFind the probability that the offspring is AA. Find the probability that the offspring is aa. What is the probability that the offspring of a heterozygous parent is homozygous? What is the probability that the offspring of a heterozygous parent is heterozygous? How does this compare with the result in the absence of mutation?arrow_forwardWhat is Genetic Drift? and what is its significance?arrow_forward
