16. In peas, tall plants (T) are dominant to short (t) and purple (P) is dominant to white flower color (p). What are the phenotypes of cross between ttPp and TtPP?

Expert Solution

Ans : tall and purple and short, purple plants will be produced on crossing ttPp×TtPP
Phenotype is the physical characteristic produced by a genotype (genetic composition).
Alternative forms of a gene are known as alleles for example 'T' and 't' are two forms of the height governing gene which produce two different phenotypic effects I.e tall and short respectively.
A dominant allele(T or W) is the one whose phenotypic effect is produced in heterozygous condition(Tt or Pp) i.e. in heterozygous condition it nullifies the phenotypic effect of the recessive allele(t or p).
A recessive allele is the one whose phenotypic effect is produced only when it is present in homozygous condition ( tt or we) because in heterozygous condition (Tt and Pp) phenotypic effect of recessive allele is nullified by the dominant allele(T or P).

In garden peas, tall plants are dominant to short plants and smooth seeds are dominant over wrinkled seeds. If two heterozygous tall plants with smooth seeds (TtRr) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? What are the gametes for each parent? What is the phenotypic ratio? What proportion of the Tall plants with smooth seeds is heterozygous for both traits?

In peas, tall (T) is dominant to short (t), yellow (Y) is dominant to green (y)...

In peas, tall (T) is dominant to short (t), yellow (Y) is dominant to green (y) and round (R) is dominant to wrinkled (r). A purebreeding plant with tall, green and wrinkled pea phenotypes is crossed to a purebreeding plant that is short and makes yellow, round peas. When peas from this F1 generation are crossed, what is the probability of obtaining a short plant that makes yellow, wrinkled peas in the F2?

In violets, purple is dominant to white and tall stems are dominant to short stems. ....

In violets, purple is dominant to white and tall stems are dominant to short stems. . A tall purple plant that is heterozygous at both loci is crossed with a double homozygous recessive plant. What is the probability of obtaining either a tall white plant or a short purple plant? What percent of the offspring are expected to be heterozygous at one or both loci? What will be the expected ratio of the F2 offspring of the F1 generation?
