What is the eccentricity of a completely flat ellipse?
DiKsa [7]
Eccentricity is a measure of how 'out of round' an ellipse is.  If the eccentricity is zero, it is not squashed at all and so remains a circle. If it is 1, it is completely squashed and looks like a line. Hope this helps. Have a nice day. Feel free to ask more questions.

sasho [114]

Answer:

a) Genotype of each parent plant= Tt

b) Genotypes of parent plants= Tt and tt

Explanation:

a) In the first cross, the tall and short progeny was obtained in almost a 3:1 ratio (78: 27). This means that both the parent plants were heterozygous for the gene of plant height. The genotype of each of the parents was Tt. A cross between Tt and Tt gives following progeny ratio=

Tt x Tt = 3 tall (1/2 TT and 1/4 Tt) : 1 short (1/4 tt)

b) In the second cross, tall and short progeny was obtained in almost a 1: 1 ratio (121: 118). This means that one parent plant was homozygous recessive (tt) and the other was heterozygous dominant (Tt).

Tt x tt = 1 tall: 1 short.
