9. In guinea pigs, rough coat is dominant (R) to smooth coat (r) and black coat (B) is dominant to white coat (b). A rough black guinea pig bred with a rough white one produces 29 rough black offspring, 31 rough white offspring, 11 smooth black and 9 smooth white. Give the genotypes of the parents, the probability for the offspring, and the actual number of each kind of offspring you would expect. Genotype of the rough, black parent

the genotype of the parent guinea pigs are as follows:

RrBb (rough, black) and Rrbb (rough, white)

Explanation:

Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.

After making the dihybdrid cross, the probability obtained for each phenotype is given below:

rough black:

rough white:

smooth black:

smooth white:

Hope that answers the question, have a great day!

because they are eaten by the frog and the frog getseaten by the snake and the snake by the eagle

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.
