One characteristic of domain archaea is their cell walls.
Answer: A trait that masks another trait is called dominant trait.
A trait is a characteristic or a morphological form that is expressed in an organism. There can be two different types of traits according to Mendelian genetics that is Dominant and Recessive trait. They are expressed due to two different forms of a gene that is called allele.
A dominant allele usually represented by capital letter like T for tall, corresponds to dominant trait and this masks the expression of recessive trait. Example- Tall plant height.
On the other hand, recessive allele is represented by small letter like t for dwarf and corresponds to recessive trait. This trait does not express in the presence of dominant allele.
Example- Dwarf plant height.
Answer:
Cellular membrane.
Explanation:
In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.
The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.
Answer:
Frequency of homozygous dominant genotype = 0.25
Frequency of heterozygous dominant genotype = 0.50
Frequency of homozygous recessive genotype = 0.25
Frequency of allele for left handedness = 0.5
And, frequency of allele for right handedness = 0.5
Explanation:
Allele frequencies:
Given that the frequency of recessive trait (left-handedness) is (q2) = 0.25
Frequency of recessive allele (q) = square root of 0.25 = 0.5
Since p+q= 1; so, p= 1-q = 1 - 0.5 = 0.5
Therefore, frequency of allele for left handedness (q) = 0.5
And, frequency of allele for right handedness (p) = 0.5
Genotype frequencies:
Frequency of homozygous dominant genotype (p2) = 0.5 x 0.5 = 0.25
Frequency of heterozygous dominant genotype (2pq) = 2 x 0.5 x 0.5 = 0.50
