2 answers:
WINSTONCH [101]3 years ago

Answer:

Case I

Genotypic Ratio – RR: Rr = 2: 2 = 1: 1

Phenotypic Ratio – All the offspring are red in color as R is dominant over r

Case II

Genotypic Ratio – RR: Rr: rr = 1: 2: 1

Phenotypic Ratio – All RR and Rr are red in color while rr is of different color, thus the phenotypic ratio is Red offspring : White offspring = 3:1

Case III

Genotypic Ratio – All  offspring’s are of genotpe rr

Phenotypic Ratio – All offsprings are of white color

Explanation:

Case I – Homozygous red bull (RR) and a heterozygous red cow (Rr)

(R ) is dominant over ( r )  

The punnet square for the cross between the Homozygous red bull (RR) and heterozygous red cow (Rr) is as follows -  

R R

R RR RR

r Rr Rr

Genotypic Ratio – RR: Rr = 2: 2 = 1: 1

Phenotypic Ratio – All the offspring are red in color as R is dominant over r

Case II - heterozygous red bull (Rr) and a heterozygous red cow (Rr)

The punnet square for the cross between the heterozygous red bull (Rr) and a heterozygous red cow (Rr) is as follows -  

R r

R RR Rr

r Rr rr

Genotypic Ratio – RR: Rr: rr = 1: 2: 1

Phenotypic Ratio – All RR and Rr are red in color while rr is of different color, thus the phenotypic ratio is Red offspring : White offspring = 3:1

Case III - homozygous white bull (rr) and a homozygous white cow (rr)

The punnet square for the cross between the homozygous white bull (rr) and a homozygous white cow (rr)  is as follows -  

r r

r rr rr

r rr rr

Genotypic Ratio – All  offspring’s are of genotpe rr

Phenotypic Ratio – All offsprings are of white color

Answer:

Explanation:

Genotype 1:

2/4 is RR so RR is 50%

2/4 is Rr so Rr is 50%

Phenotype:

Not enough info for that

Genotype 2:

1/4 is RR so RR is 25%

2/4 is Rr so Rr is 50%

1/4 is rr so rr is 25%

Phenotype:

?

Genotype 3:

4/4 is rr so rr is 100%

Phenotype:

??

Archaea differ from bacteria in that archaea
o-na [289]

Answer:

The correct answer is A) Have diverse cell wall compositions

Explanation:

Both bacteria and archaea comes under prokaryotes because they both lack a membrane-bound nucleus. The difference between archaea and bacteria is in their cell wall composition.

The bacterial cell wall is made up of peptidoglycan and the archeal cell wall is made up of pseudo-peptidoglycan. In bacteria, peptidoglycan contains N acetyl muramic acid and N acetyl glucosamine unit but in archaea, the N acetyl muramic unit is replaced by some other unit and the linkage of two units is also different in archaea. So the right answer is A.

Natali [406]

Answer:

C. Synthesis of organic molecules

Explanation:

According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
