ad-work [718]

Answer:

1/16

Explanation:

Sickle-cell disease is caused by a homozygous recessive genotype <em>dd</em>.

A man and a woman both heterozygous Dd will have the following offspring:

  • 1/4 DD
  • 2/4 Dd
  • 1/4 dd

The probability of having a <em>dd</em> child with Sickle-cell disease is 1/4. Each time they have children the gamete combination is random, so the genotype of the second child is independent from the genotype of the first child.

According to rules of probability, if two events are independent from each other, the probability of both happening is calculated by multiplying the individual probabilities of each.

Therefore the probability of having the first two children with the disease is 1/4 x 1/4 = 1/16.

Bacteria are involved in increasing the fertility of the soil by fixing atmospheric nitrogen and thus provide plant with nitrogen. In return, the bacteria make their homes in what usually become nitrogen "nodules" along plant roots. The plant gets food, the bacteria gets shelter, everybody wins.

PLEASE HELP ASAP<br><br> how does the ribosome read the mRNA?
ValentinkaMS [17]

Answer:

A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).
