Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2
2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2
3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4

Clostridium, Bacteroides, and the methane-producing archaea (methanogens), are called obligate anaerobes because their energy-generating metabolic processes are not coupled with the consumption of oxygen.
Answer:
Medical uses: The field of genetic engineering is making progress rapidly and it has helped doctor's to fight many challenging diseases. One of the medical use of genetic engineering is the production of insulin by genetic engineering and also the production of vaccines through this technique.
Agricultural uses: The field of biotechnology can change the life of farmers once it is fully known that the genetically engineered crops cannot harm the humans. One of the uses of genetic engineering in agriculture is the production of crops containing increased nutrition. For example,Golden rice which carries vitamin A in it.
Environmental uses: Genetic engineering is used to clean the Earth by producing genetically engineered microorganisms which can not only break down waste but also can degrade plastics.
This should be an example of genetic drift.
The brown spotted deer would spread their genes more than the white spotted ones which would eventually lead to them completely overpowering genetically the white deer in future generations.
Carnivores (meat eaters): lion, wolf, polar bear. herbivores (plant eaters): cows, beaver, deer. omnivores (both meat and plant eaters): bears, humans, hedgehogs.
