In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

                                Observed(o)   Expected(e)   (o-e)    $(o-e)^2$      $(o-e)^2/e$

Green-melon plant        53                    47               6          36             0.766

Yellow-melon plant        41                    47              -6          36             0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Which of the following types of reproductive barriers separates a pair of insect species that could interbreed except that one m
Arte-miy333 [17]

Answer:

Answer is B, habitat isolation.

Explanation:

Habitat isolation can simply be explained as a situation whereby two insects or organisms of the same species, that have the ability to meet and reproduce could not, because they are living in different habitats.

These different habitats might even be in the same geographical location or area. That is, one insect might be living in or on the surface of the water, and the other living in the soil or the tree. Due to this effect, the insects are unlikely to meet and reproduce.

Answer:

Charles Darwin

Explanation:

Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.

In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.
