Aspecies of snail has 24 chromosomes - 12 pairs - in each somatic cell. how many chromosomes are there in a snail egg cell? a snail sperm cell?

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.

An organ system consists of a group of organs that performs specific functions necessary for the survival of an organism. humans have eleven different organ systems: integumentary, skeletal, muscular, nervous, endocrine, circulatory, lymphatic, respiratory, digestive, urinary, and reproductive. discuss the function of neurons, the brain and the spinal cord within the human nervous system while explaining the interrelationship of each organ.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
