Answer:

The options are missing, the options are:

(a) the ratio of round to wrinkled would have been unpredictable and change each generation

(b) all of the seeds would have displayed the dominant trait, round

(d) an inversed 3:1 ratio, wrinkled:round

(e) no offspring would have been produced, so there would be no ratio

The correct answer is A

Explanation:

Mendel proposed that alleles of a gene separates into gametes during gamete formation. He called this Law of Segregation. He also stated that in an heterozygous organism, each different allele separates into gamete will equal frequency. He was able to predict the phenotypic ratio of 3:1 for the F2 generation using this principle and it proved right.

If his principle of segregation were false, it would have been impossible to predict the phenotypic outcome of the offsprings i.e. in what proportion each trait will occur. This unpredictability would have changed the ratio of the offsprings in each generation. For example, in the case of seed shape gene, if the round and wrinked alleles didn't separate in equal frequencies, it would be impossible to come up with a prediction of 3:1 ratio of round to wrinked seeds.

Describe how living things use anaerobic respiration to generate energy.

Mrac [35]

Anaerobic respiration is the process by which some organisms produce energy in the absence of oxygen. Instead of oxygen, organic and inorganic molecules are used as electron acceptors. One example of anaerobic respiration is fermentation.
In latic acid fermentation, one molecule of glucose undergoes glycolysis to produce two molecules of pyruvate. The two molecules of pyruvate then undergo fermentation to produce two molecules of lactate. The lactate will be transported to the liver. The lactate can be reconverted to pyruvate and utilized for energy. Latic acid fermentation occurs in the muscles.

yarga [219]

Answer:

A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only. A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.

Explanation:

and the tow words have a prefix and mono means one and the dihy means two. a hydrate containing two molecules of water.
