elena-s [515]

Answer:

If the question is referring to Mendel's postulates, all options are correct

Explanation:

Gregor Mendel discovered that certain components he called UNIT FACTORS determine inheritance. This unit factors were later described to be genes in modern genetics. He discovered that an organism receives two forms of this unit factors from each parent, which he called ALLELES. In his experiments, he observed that one of the pair of alleles have the ability to mask the expression of its variant pair. He called the allele that masks, DOMINANT allele while the allele that is masked, RECESSIVE allele.

During his cross experiment, he discovered that the alleles of a gene (unit factor) separates into gametes, he called this LAW OF SEGREGATION. He notably discovered in his cross involving two different characters that the segregation of the alleles of one gene into gametes does not influence the segregation of the alleles of the other gene. He termed this his LAW OF INDEPENDENT ASSORTMENT.

Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentca

postnew [5]

Answer:

can lead to natural selection

Explanation:

<h2></h2><h2>Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>

This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>

So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "<u>Nature selected"</u><u> </u>the better fit organism.
