Answer:
15/16 or 93.75%
Explanation:
The proportion of the offspring of the cross expected to be red would be 15/16 or an equivalence of 93.75%.
Red fruit color is conditioned by the presence of A_, B_ or A_B_ alleles. In the absence of both dominant alleles, the condition is white. AaBb was crossed with AaBb.
AaBb x AaBb
Progeny' Genotype Phenotype
1 AABB red
2 AABb red
2 AaBB red
4 AaBb red
1 AAbb red
2 Aabb red
1 aaBB red
2 aaBb red
1 aabb white
Hence, the proportion of the offspring that are expected to be red is 15/16 or 93.75%.
See the attached image for the Punnet's square analysis of the cross.
In humans, red blood cells have a number of proteins embedded in the cell membrane. One type of protein, the Rh factor, is controlled by a single gene and is either present or missing from the red blood cells. If present, the individual has the Rh+ phenotype. If missing, the individual has the Rh− phenotype. Rh+ is the dominant to Rh−. Suppose that, in the Yoruban population, the frequency of the Rh− phenotype is 0.01.0.01. Using the Hardy–Weinberg equations, calculate the frequency of the Rh+ allele to at least two decimal places.
Answer:
the answer would be that the frequency of the allele Rh + = 0.6
Explanation:
the frequency of the Rh value is incorrect, the value must be expressed in an integer that can have decimals but not a meaningless numerical sequence(0.01.0.01?), however, an exercise is performed taking the frequency value 0.16 as an example for the development of subsequent
we can start from the formula taking into account that the population is in Hardy-Weinberg equilibrium
p2 + 2pq + q2 = 1.0
the above is based on the fact that
p2 is considered as the dominant homozygous ratio
q2 as the proportion of recessive homozygotes
2pq as the proportion of heterozygous individuals
knowing that the Rh phenotype is recessive and has a value of 0.16, we replace obtaining
q2 = 0.16 or q = 0.4
where solving the equation
p + q = 1
p = 1- 0.4 = 0.6
the answer would be that the frequency of the allele Rh + = 0.6
How do human diseases caused by bacteria and diseases caused by viruses react to antibiotics?
A. Neither responds to antibiotics.
B. Both respond to antibiotics.
C. Viral diseases respond to antibiotics; bacterial diseases do not.
D. Bacterial diseases respond to antibiotics; viral diseases do not.
Answer:
D
Explanation:
viruses don't react to antibiotics because the target of antibiotics is bacteria and their constituents however viruses react antiviral because their to them.
Human diseases caused by bacteria and diseases caused by viruses react to antibiotics as D. Bacterial diseases respond to antibiotics; viral diseases do not.
Explanation:Antibiotics are substances that kill or inhibit the growth of bacteria. They work by targeting specific structures or processes in bacterial cells, such as cell walls or protein synthesis. Viruses are different from bacteria. They are much smaller and they rely on host cells to reproduce. As a result, antibiotics do not have any effect on viruses.
Antibiotics are effective against bacterial infections, not viral infections. Bacteria are distinct organisms with cell walls, making them vulnerable to antibiotics that target specific cellular processes. Viruses, on the other hand, are not considered living cells and lack these targets. They require antiviral medications, which are different from antibiotics, for treatment.
