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.  

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

b. the carbon cycle ensures living things have a source of hydrogen
