Answer:

Parent 1 = RrBb

Parent 2 = RrBb

Explanation:

This question involves two genes in guinea pigs. The allele for rough coat (R) is dominant to smooth coat (r), and the allele for black coat (B) is dominant to white coat (b).

According to this question, two rough black guinea pigs when bred together produced two offsprings. One of the offsprings is rough white (R_bb) and the other is smooth black (rrB_). This means that, to produce such offsprings, the parents must be both heterozygous for both genes (RrBb). Please find the punnet square for this cross attached

Plant A and Plant B are heterozygous for a gene that expresses their tall trait (Tt). Upon crossing, what is expected in the off
Oksi-84 [34.3K]
The answer is 75% of offspring will be tall and 25% of offspring will be short.

If:
T - the dominant allele for tall trait
t - the recessive allele for short trait

Then:
TT - dominant homozygote (tall)
Tt - heterozygote (tall)
tt - recessive homozygote (short).

In the cross of two heterozygotes Tt x Tt <span>75% of offspring will be tall and 25% of offspring will be short:

Parental generation:        Tt     x     Tt
Offspring generation:   TT    Tt    Tt    tt

Thus, 3 out of 4 (=3/4=75%) offspring are tall (1 TT and 2 Tt) and 1 out of 4 (=1/4=25%) offspring is short. Speaking of genotypes, 1 out of 4 (=1/4=25%) is dominant homozygote (TT), </span>2 out of 4 (=2/4=50%) is heterozygote (Tt), and <span>1 out of 4 (=1/4=25%) is recessive homozygote (tt).</span>

Chronic lymphocytic leukemia (cll) commonly causes hypogammaglobulinemia. this makes clients with cll more susceptible to infect
andrew-mc [135]

Chronic lymphocytic leukemia or the CLL  is among the most common type of leukemia affecting the adults. The lymphocytic leukemia starts in the lymphocytes. Lymphocytic leukemia is different from the lymphoma (which also occur in the lymphocytes) as it only occurs in the bone marrow and the blood. The person suffering from CLL is susceptible to an array of infections. Among the various infectious agents, the CLL patient is the most susceptible to the Staphylococcus aureus. This agent causes skin infections, pneumonia, toxic shock syndrome and many other life threatening diseases. The person becomes susceptible to its attack as the immunity of his is weakened beacuse of the damage to the lymphoctic cells.
