Match the following terms and definitions. 1.breeding of individuals that have genes for two different characteristics codominance 2.a grid system used to predict possible combinations of genes due to random fertilization incomplete dominance 3.a condition in which both alleles are dominant multiple alleles 4.when more than two alternatives exist for a gene dihybrid cross 5.a condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype punnett square

1. Dihybrid cross-refers to the breeding of individuals, which possesses genes for two distinct features. It is termed as dihybrid as one is considering a cross in between two distinct traits.  

2. Punnett square refers to a grid system, which is used to determine the probable combinations of genes because of random fertilization. The Punnett square helps one to determine an outcome of breeding or a cross.  

3. Codominance refers to the condition in which both the alleles are dominant. It comprises the alleles that exhibit the tendency of dominating at a similar time, and when an organism is heterozygotic, both the alleles are articulated.  

4. Multiple alleles refer to a phenomenon in which more than two alternatives prevails for a gene.  

5. Incomplete dominance refers to a condition in which none of the pair of alleles is recessive or dominant, thus, the traits get mixed in the phenotype.  

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
