Answer:
1/4
Explanation:
Cystic fibrosis is a recessive disorder and therefore, is expressed only in homozygous recessive genotype. Let's assume that the allele "c" is responsible for the disease in the homozygous state. Since the couple already has a child with cystic fibrosis (cc), they both are heterozygous carriers for the disease.
The genotype of male and female each is "Cc". A cross between Cc x Cc gives progeny in the following phenotype ratio=1/4 diseased: 1/2 normal carriers: 1/4 normal. Therefore, the probability of getting a diseased child for them is 1/4.
Answer:
A
Explanation:
crossing over is the ability to do so
Answer:
b. Scientists are interested in incorporating knowledge of how dolphins accurately transmit and receive information into the design of their tsunami detection networks. The scientists will probably want to investigate if there are any impacts of these networks on dolphins in the area.
Explanation:
Scientists want to study communication between dolphins because these animals are able to establish efficient communication with each other even over long distances. With the knowledge of this communication, scientists can incorporate similar factors into their tsunami information transmission system, so it will be easier to accurately transmit and receive information in the design of their tsunami detection networks.
However, it is necessary for scientists to include in the study, the possible impacts that this system of transmitting information about tsunamis can have on the dolphin population.
In summary, we can say that scientists are interested in incorporating knowledge of how dolphins transmit and receive information accurately in the design of their tsunami detection networks. However, scientists must investigate whether there is any impact of these nets on dolphins in the region.
