ra1l [238]

Explanation:

Hemoglobin is a blood hemoprotein, with a molecular mass of 64,000 g / mol (64 kDa), of a characteristic red color, which transports the dioxygen (commonly called oxygen), O2, from the respiratory organs to the tissues, the dioxide of carbon, CO2, from the tissues to the lungs that eliminate it and also participates in the regulation of blood pH, in vertebrates and some invertebrates.

Hemoglobin is a quaternary structure protein, which consists of four subunits. This protein is part of the hemoprotein family, since it has 1 heme group in each subunit

Hemoglobin is a tetrameric protein, which consists of four polypeptide chains with different primary structures. ... Each hemoglobin polypeptide chain is attached to a heme group to form a subunit. The four subunits of hemoglobin in its quaternary structure form a tetrahedron.

Assume that genes A and B are 50 map units apart on the same chromosome. An animal heterozygous at both loci is crossed with one
fomenos

Answer:

Explanation:

The homozygous recessive individual can only produce 1 type of gamete (<em>aabb</em>).

The heterozygous individual can produce 8 types of gametes, of which 2 are parental and the rest are recombinant.

Genetic distance (m.u.) = Frequency of Recombination (%)

If the distance between genes A and B is 50 m.u., 50% of the gametes produced by the heterozygous individual, and therefore the offspring, will have recombinant phenotypes.

Without knowing that the genes are located on the same chromosomes, I'd think they are on different chromosomes, because you would get the same result: 50% recombinant offspring.

Whenever the genes on the same chromosome are separated by at least 50 m.u., or they are in different chromosomes, crossing over between them can happen with no restrictions and they will behave as independent of one another.
