PLEASE HELP ME! Speciation Worksheet

Identify which type of reproductive isolation is being show in each example below:
G = geographic T = temporal B = behavioral

1. Two species of fireflies come out between the hours of 9-11 p. m. Each species has a unique
pattern of flashes that attracts a mate.
2. Two species of plants sprout from the ground at different months in the year.
3. Two species of frogs call from the water at the pond’s edge for a female.
4. Two species of squirrels get stranded on either side of a grand canyon.
5. Two species of mountain lions live in a forest on either side of a large river.
6. Two species of songbirds call from a tree for a potential mate.
7. Two species of bowerbirds construct elaborate nests to attract a mate.
8. Ten species of finches live on the Galapagos Islands.
9. Two species of foxes mate in different seasons.
10. Two species of beetles come out at different times of the day

Will mark brainliest! 1.) jan’s sister and mother have both had breast cancer. she is wondering if she should undergo genetic testing to check for a mutation of the brca1 gene. a mutation in the brca1 gene is commonly associated with, but not guaranteed to cause, breast cancer. the presence of a mutation increases a patient’s chances of getting breast cancer to about 85 percent, compared to a 13 percent risk in the general population. costs may vary, but most labs charge patients or their insurance companies less than $3,000 to sequence the brca1 to look for mutations. do you think that jan should undergo genetic sequencing? explain your answer. (2 points) what are potential pros and cons of having such tests done? (5 points) describe how the availability of genetic sequencing can affect the frequency of genetic diseases in individuals and populations. (3 points) 2.) scientists have developed genetically engineered plants that are pest-resistant. by adding genes to the plant’s dna, they become toxic to insects (but not to plants or animals). this means that these plants may not need to be sprayed with pesticides to ward off the insects. would you be willing to eat these genetically altered crops? explain your answer. (5 points) what are some possible impacts (positive or negative) of this genetically engineered plant on the environment, society, and individuals? (5 points)
