Each parent contributes one allele describes the influence that parents have on whether or not offspring inherit a genetically inherited trait.
Explanation:
Allele is a form of gene present on the chromosome. Human have 2 alleles for a trait on a chromosome. Each parent contributes one of its allele to the progeny.The alleles for the gene are present on the same locus of chromosomes.
The alleles are either dominant or recessive. The contribution of alleles and the expression of trait decide the alleles of offspring.
The phenotype is determined by the allele expressed as short or tall and human ABO blood type.
An allele is sequence of DNA. The organism having two same alleles are homozygous and having two different alleles are heterozygous.
Answer:
<em>Impacts from human activity on land and in the water can influence ecosystems profoundly. Climate change, ocean acidification, permafrost melting, habitat loss, eutrophication, stormwater runoff, air pollution, contaminants, and invasive species are among many problems facing ecosystems.</em>
The answer is ‘in the dermal papillae of hairless skin’. Dermal papillae is the layer of the skin (upper dermis) with numerous blood vessels and nerves that serve the epidermis of the skin. Tactile corpuscles (nerves) are mostly found in this region and occur mostly in hairless thick skin such as in finger and toe tips.
