Consider the genes for pea color (the "y" gene) and pea height (the "t" gene). for the "y" gene, the y allele = yellow peas and the y allele = green peas; for the "t" gene, the t allele = tall peas and the t allele = short peas. draw and fill in a punnett square for a dihybrid cross of two pea plants that both have the genotype yy tt. what is the expected phenotype frequency of yellow and tall offspring?

9/16= tall and yellow offspring

Explanation:

Two dihybrid pea plants for color and height are crossed to obtain the progeny. The genotype of both the parents is "TtYy".

Each of the dihybrid parent will form four types of gametes in 1:1:1:1 ratio= TY, Ty, tY and ty. A random fusion of gametes from both the parents would give a progeny in following phenotype ratio=

9 tall and yellow: 3 tall and green: 3 dwarf and yellow: 1 dwarf and green

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
