If you look at a Punnet square of this, you can determine the possible phenotypes. Lets assign B for brown eyes, b for blue eyes, H for right hand and h for left hand.
The mother is blue eyed and left handed which are both recessive traits. This means that her genotype would be bbhh. Now the father is heterozygous for both, which means he has a dominant and recessive allele for each trait. His genotype would then be BbHh
The Punnet square should look like the table below:
Mother:bbhh
Father:BbHh
bh bh bh bh
BH BbHh BbHh BbHh BbHh
Bh Bbhh Bbhh Bbhh Bbhh
bH bbHh bbHh bbHh bbHh
bh bbhh bbhh bbhh bbhh
Based on the Punnet square, you have 4 possible genotypic combinations and 4 possible phenotypic combinations.
BbHh: Brown-eyed, right-handed
Bbhh: Brown-eyed, left-handed
bbHh Blue-eyed, right handed
bbhh Blue-eyed, left-handed
Continetal drift is land masses that mover over the surface of the earth.. for example a land mass might move from an equatrioal region of the earth and then to an antarctic region so therefore it recives an antarctic climate instead of a equatrial one....
Answer:
The protons and the neutrons are found in the nucleus of an atom.
Explanation:
Atoms are best described as the smallest unit of any matter.
Protons can be described as part of an atom which carries a positive charge. The protons are enclosed in the nucleus of the atom.
The neutron is the part of the atom that carries zero charge. The neutron is also enclosed in the nucleus of the atom.
The electrons can be described as the part of an atom that carries a negative charge. The electrons move around the nucleus in orbits.
To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:
R= tall stalk
r= short stalk
The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.
Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.
Answer:
The different species present in an ecosystem make the ecosystem balanced. The species of an ecosystem interact with one another in one form or the other. For example, the presence of a plant species will provide food for the abundant types of herbivores present in an ecosystem. A predator might feed on many types of preys. Hence, the presence of different preys will reduce the chances of a species from becoming wiped out from the ecosystem. Hence, all the organisms in an ecosystem are dependent on another in some way or the other.
