What law best explains why an organism with Tt will show only the dominant phenotype
nirvana33 [79]

This is the law of dominance in genetics. The dominant allele will mask the effects of the recessive allele and therefore will be the visible trait of the phenotype. Most often, the dominant allele codes for functional proteins, while the recessive does not code for functional proteins. Dominance in genetics is significant in Mendelian inheritance.

A gene has 2 alleles, R & B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls loo
irakobra [83]

Answer:

5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

8.)Repeat the same thing in 7 but use different numbers

RR=10

R=10x2

=20

RB=10

R=10

Total R= 20+10

=30

Why would bacteria that are normally kept under control, become a possible problem after having coronavirus?
Fittoniya [83]

Since due to having the coronavirus, the immune system is already tired of fighting off such a tough disease. Since it's so weak, one small bacteria can make your body react to it in ways you wouldn't think it may, because the immune system isn't working much.
