On the basis of the data for the genotype, the types of gametes formed and their proportion, for the following pairs: a. AABB b. AaBB c. Aabb d. AaBb One gene has the alleles A and a whereas another gene has the alleles B and b. A and B represent the dominant alleles while a and b represent the recessive alleles. Introduction: When a homozygous allelic pair divides, it forms the same genes with both coding either for dominant genes or for recessive genes. When a heterozygous allelic pair divides, it forms two genes that code for dominant genes and recessive genes. In the case of independent assortment, each characteristic separate into gametes independently when there are two or more characteristics to be inherited.

b. AaBB

c. Aabb

d. AaBb

One gene has the alleles A and a whereas another gene has the alleles B and b. A and B represent the dominant alleles while a and b represent the recessive alleles.

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…
