Explanation:
Incomplete dominance is a phenomenon in genetic inheritance that occurs when the two alleles of a gene seem equally effective in their influence on a trait. It is a form of Intermediate dominance in which one allele for a specific trait does not completely mask the expression of its paired allele, as opposed to Mendel's law of dominance. Incomplete dominance results in a third phenotype different from the parent phenotypes but a combination of both.
In incomplete dominance, the intermediate/resulting phenotype is the heterozygous genotype.
Gregor Mendel discovered this concept of incomplete dominance in the flower of four o'clock plants when he crossed a purebred (homozygous) red-flowered (RR) with a purebred (homozygous) white-flowered plant (rr) to get F1 offsprings that are all heterozygous but have pink flowers (Rr). He later self-fertilized the F1 offsprings to produce a phenotypic ratio of 1:2:1 consisting of 1 red, 2 pinks, 1 white flower respectively.
This showed that the allele for red flower (R) is incompletely dominant over the allele for white flower (r), hence, producing an offspring with a different trait that arose from the blending of the two phenotypes.
Incomplete dominance is similar but different from co-dominance in the sense that, in co-dominance, both alleles/traits are expressed completely in the new phenotype produced while in incomplete dominance, the new phenotype is just a blending of the two phenotypes.
Apoptosis is programmed cell death. The body is this to get rid of unneeded or abnormal. The body will get rid of cells with damaged DNA before they can become cancerous.
Answer:
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. ... Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
