In pea plants, tallness (T) is dominant to shortness (t). What is the predicted genotypic ratio of the offspring if a homozygous
tino4ka555 [31]
First, to answer this question, you need to draw a Punnett square. So you put the homozygous short alleles (tt) on top of the square, and the heterozygous tall alleles (Tt) on the left side of the square (or vice versa, it doesn't really matter).

When you create the Punnett Square, you then perform the cross between the two plants' alleles. I cross t with T and that gives me Tt. Same with the next one, t and T becomes Tt. Then, I cross t with t and that gives me tt. Same with the next one, t and t becomes tt.

So, the answer here would then be c. 50 percent Tt, 50 percent tt. You might say, well, couldn't answer d also work? Answer d could only work if the question was asking for the phenotypic ratio of the offspring. Then you could say 50% tall, 50% short. But the question asks for the genotypic ratio, so it would instead be c. 50 percent Tt, 50 percent tt.

Hope this helps!

Which clinical manifestation, when found in newborns, may indicate the presence of cystic fibrosis?
SCORPION-xisa [38]

Meconium ileus, in newborns, may indicate the presence of cystic fibrosis

Cystic fibrosis is a genetic disorder mainly associated with cells capable of producing mucus. These cells are found in sweat glands, digestive system and lungs belonging to respiratory system. Thus, the abnormality in mucus production, in sticky and thick nature, disrupts the normal functioning of human body. They block the ducts and tubes, which can result in life threatening condition.

The mutation responsible for cystic fibrosis occurs in the gene CFTR, which is abbreviated form of Cystic fibrosis trans membrane conductance regulator. The primary function of gene is to regulate the exchange of fluids and salts present in the cells.

Meconium ileus refers to the inability of bowel movement in the newborn. This occurs due to thick and sticky mucus, which is indicative of cystic fibrosis, as discussed above.
