When a BB male and a Bb female are crossed, 50% BB and 50% Bb genotypes are produced and a 100% black phenotype.

The entire number of genes that an organism receives from its parents makes up its genotype. Alleles, which are pairs of these genes, are found. One gene is dominant and one gene is recessive in each allele.

The dominant gene is always expressed in a cross if it is present. Only when a pair of alleles is made up of two recessive genes does the recessive gene express itself. In this instance, the white fur is subordinate to the black fur. White fur is represented as b, while black fur is represented as B.

We can see that when we cross the BB male and Bb female, we will get a genotype that is 50% BB and 50% Bb, as well as a phenotype that is 100% black fur.

Parents: BB x Bb

Gametes: B, B, and B, b

Offspring: BB, BB, Bb, Bb

The genotypic ratio = 1:1

The phenotypic ratio = 1:0

Genotype probabilities:

P(BB) = 2/4 = 0.5 or 50%

P(Bb) = 2/4 = 0.5 or 50%

Reticulate and elementary bodies are two forms of A. Mycoplasma. B. Caulobacter. C. Chlamydia. D. Myxobacteria.
Aleksandr [31]

Answer:

C. Chlamydia. is the correct answer.

Explanation:

Chlamydia is a bacterial sexually transmitted disease, caused by obligate intracellular Chlamydia trachomatis.

In the life of chlamydia, there are two stages of developmental(Reticulate and elementary bodies are two forms of Chlamydia.)

The elementary body is the infectious substance, they are non replicating and have a rigid outer membrane that binds to the receptors present on the host cell and it initiates the infection and due to the rigid outer membrane there, no fusion between the phagosome and the lysosome hence oppose the intracellular killing.

Reticulate bodies are the metabolically active form of a chlamydia and non-infectious.

How does inorganic nitrogen from the atmosphere<br> (N2) get into living systems?
lawyer [7]

Answer:

When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.

Explanation:

Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.

Cloaca in vertebrates, common chamber and outlet into which the intestinal, urinary, and genital tracts open. It is present in amphibians, reptiles, birds, elasmobranch fishes, and monotremes.  Cloaca is not present in placental mammals or in most bony fish.
