The answer would be C, double fertilization produces a triploid zygote and a tripped endosperm!
The answer is B and I need 20 characters so I am typing random words
Answer:
Suffling of genetic material increases genetic variation in offspring which is important for evolution.
Explanation:
Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.
In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.
Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.
Answer and Explanation:
Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history. Paleontologists are still searching these areas.
An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.
You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.
Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.
