Haploid(genetics) an organism or cell having only one complete set of chromosomes, represented as "n" Diploid(genetics) an organism or cell having two sets of chromosomes or twice the haploid number, represented as "2n" Chromatidone of two identical "sister" parts of a duplicated chromosome, combining two would create a whole chromosome chromsomeStructural unit of genetic material consisting of double stranded DNA and proteins, made of two chromatids sister chromatidsReplicated forms o...

In certain plants, tall is dominant to short trait. If a heterozygous plant is crossed with another heterozygous (tall) plant, what is the probability that the offspring will be short? A) 1/2 B) 1/4 C)0 D) 1 E) 1/6 - 1/4 The parents' genotype is Tt because they are both heterozygous tall. The punnet square would indicate 3/4 chance that the offspring will be tall (TT, Tt, Tt) and 1/4 chance they will be short (tt) A cross between pea plants with red flowers and plants with white flowe...
