The alleles for short will be tt and for tall TT

Explanation:

The recessive alleles are written in small alphabets in Mendelian genetics so the alleles for short is tt.

They must be homozygous to express the phenotypic trait of short height in progeny.

tt = short

suppose if a homozygous tall and homozygous short is crossed

all the progeny will be heterozygous tall. Tt 4:0 ( no short progeny)

Suppose Tt is crossed with Tt

If heterozygous tall are crossed then genotype ratio will be

Tt:TT:tt

2:1:1

This means only 25% will be short.

e-lub [12.9K]

Answer:

Probably B

Explanation:

They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.

What is the net gain in ATP in glycolysis?
Butoxors [25]

Glycolysis, the first process in cell respiration, produces four ATP, but it uses two of the ATP molecules, therefore producing a net two ATP molecules. The process also yields two molecules of NADH.Glycolysis begins with glucose and breaks it down into two molecules of phosphoglyceraldehyde.


Hope this helps
