Answer:
The correct answer would be option D) no gametes.
Explanation:
The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.
Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.
The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.
Thus, the correct answer would be option D) no gametes.
Carbon<span> Dioxide is the by-product of </span>emissions<span> from our vehicles, heating our homes, using electricity and from other activities in our daily lives (explained more in the 6 steps to go green). It is also the leading greenhouse gas that contributes to climate change.</span>
Answer:
A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only. A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.
Explanation:
The continental margin<span> is the zone of the ocean floor that separates the thin oceanic crust from thick </span>continental<span> crust. Together, the </span>continental<span> shelf, </span>continental<span> slope, and </span>continental<span> rise are called the </span>continental margin<span>. </span>Continental margins<span>constitute about 28% of the oceanic area.</span>
A single point mutation<span> can change the whole DNA sequence. Changing one purine or pyrimidine may change the amino acid that the nucleotides code for.</span>Point mutations<span> may arise from spontaneous </span>mutations<span> that </span>occur<span> during DNA replication.</span>
