Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
Answer:
Chloroplasts are only found in the parts of the plant that are capable of photosynthesis. The majority of chloroplasts are found in the leaves of the plant because these structures have the greatest surface area for absorption. The outer part of a plant stem may also contain chloroplasts.
Explanation:
Answer:
Half would have the genotype Aa.
Explanation:
Given that the genotype of both of the parents was "Aa"; both parents would make two types of gametes. The 50% gametes from each parent would carry allele "A" while the rest 50% gametes from each parent would carry allele "a".
The random fusion of gametes of two parents would give the progeny with genotype ratio 1/4 AA: 1/2 Aa: 1/4 aa.
Answer: Factors affecting biome type include latitude, humidity, and elevation. Terrestrial biomes include the tropical rainforest, chaparral, and taiga.

<span>The population dynamics of the Warbler species differ from what's documented by Scott Sillett and colleagues one migration issues.
The Warbler species are non migratory species, while Scott Sillet and colleagues have been studying migratory species. The Warbler species were even taken to other islands, in some cases, in order to give them the </span>security of additional breeding populations, this because their population dynamics is not a migratory one. The studied species by Scott Sillet and colleagues, on the other hand, have migratory population dynamics: they pass their Summer time in <span>New Hampshire and and their Winter time in Jamaica.</span>
