Fatty acid metabolism disorder is an autosomal recessive disorder. Two unaffected parents have 6 children - all of whom are unaf
Nadusha1986 [10]

Answer:

There are only 2 possible genotypes for the mother, FF and Ff.

Explanation:

Because it is an autosomal inheritance, this case F will be the dominant allele and f the recessive allele, where f produces Fatty acid metabolism disorder. If the mother does not possess the disorder, she must possess at least one dominant allele for that specific gene. However, for the other allele, we cannot assure that it is dominant, since it can be recessive and not express itself either in her or in the offspring, because of the father we also only know his dominant allele.

Climate warming trends allow plant and insect species to inhabit larger ranges. True or false?
attashe74 [19]

The right answer is True.

At the global level, climate change will contribute to the disruption of the Earth's natural ecosystems, which could lead to the extinction of wild animal species and plants. It is mainly the impact of climate change on habitat and ecosystems that will dictate the impacts on biodiversity (by expanding them or the opposite).

Climate change will profoundly affect agricultural and forestry production. The effects in terms of production potential will be very variable depending on the regions and plant cover. They can result in an overall tendency for moderate stimulation in temperate climates and for limited warming at 2 ° -3 ° C.
