Answer: 1). TT and Tt Parental genotypes are TT & Tt and as well as offspring genotypes are also TT & Tt. 2). Genes Genes (factors) assort independently during formation of gametes 3). Round, yellow seeds only RRYY x RrYy RY Ry rY ry RY RRYY (Round, yellow) RRYy (Round, yellow) RrYY (Round, yellow) RrYy (Round, yellow) 4). Mendel The present understanding of how inherited traits are passed between generations comes from principles first proposed by Gregor Mendel. 5). Environmental conditions. The characters determined by genes are transmitted from one generation to other whereas characters determined by environmental conditions may or may not be inherited from one generation to other. 6). Incomplete dominance Red (RR) x White (rr)---parents Pink (Rr) ----offspring 7). Codominance Alleles that are masked or hidden by dominant alleles are known as recessive alleles. In some situations, both alleles are expressed equally. A genetic scenario where neither allele is dominant or recessive and both get expressed is known as codominance.
