In cats the allele for short hair is dominant over the allele for long hair. A short haired male and long haired female have kit
SCORPION-xisa [38]

Answer:

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Use the Punnett square to predict the genotype for the parent organism whose genotype is unknown and
Katyanochek1 [597]

Answer: The genotype for the parent organism whose genotype is unknown is Ff.

Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.

The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).

A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).

Ff x ff = Ff, Ff, ff and ff.

Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.

See the attached punnet square for more information

What are TWO functions of citric acid in the feta cheese? What are the TWO functions of agar in the feta cheese?
Vinvika [58]

Answer:

The following are the two functions of citric acid in the feta cheese:  

1. Coagulation, that is, the chemical reaction of citric acid with proteins in milk leads to separation of curd and whey.  

2. The citric acid functions as a chelating agent, which is required for syneresis, that is, for controlling the moisture content.  

The following are the two functions of agar in the feta cheese:

1. Feta means to slice, and agar offers sliceable texture to the feta cheese as it produces a solid gel-like composition.  

2. It is a vegetarian alternative for gelatin and exhibits higher gelling properties.
