Geneticist have determined that the majority of individuals in an isolate island population have blood type b. type a blood is f

Oksi-84 [34.3K]

The correct answer is genetic drift has minimized the frequency of type A individuals.

Usually, genetic drift takes place in small populations, where infrequently happening alleles encounter with a greater chance of getting lost. Once it starts, genetic drift will continue until the involved allele is the only allele present in a population at a specific locus or until the allele involved is lost.

In the given case, allele A is lost due to genetic drift phenomenon.

Put the steps of zygomycete sexual reproduction in the right order. Start with the production of multinucleate gametangia at the

Vesnalui [34]

Answer:

Choice 4 of 5. Hyphae produces multinucleate gametangia

Choice 1 of 5. Gametangia fuse

Choice 2 of 5. Karyogamy occurs and zygosporangium develops

Choice 5 of 5. A dark, thick-walled zygospore develops

Choice 3 of 5. Meiosis occurs to produce haploid spores

Explanation:

The steps of zygomycota sexual reproduction are;

Germination step; Hyphae produces multinucleate gametangia

Plasmogamy step; Gametangia fuse when compatible mating types of mycelia are brought close to each other by the formation gametangia between

The fusion of the nuclei results in the formation of zygosporangium that has multiple haploid nuclei and a thick wall

Karyogamy step; A zygote having multiple diploid nuclei is formed by the fusion of nuclei

Germination and Meiosis step; The sporangia grows and haploid spores are produced

Therefore, we have;

Choice 4 of 5. Hyphae produces multinucleate gametangia

Choice 1 of 5. Gametangia fuse

Choice 2 of 5. Karyogamy occurs and zygosporangium develops

Choice 5 of 5. A dark, thick-walled zygospore develops

Choice 3 of 5. Meiosis occurs to produce haploid spores

What is the primary product of light independent reactions

SOVA2 [1]

The primary products of the light independent reactions (after one turn of the cycle) are:

a) two G3P molecules

b) three ADP

c) two NADP+

However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions. Each G3P molecule is composed of three carbons.

For the Calvin cycle (Light independent cycle) to continue, 5 out of the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there remains only one carbon for the next turn of the cycle.

One molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.
