Johann gregor mendel's work in genetics focused on traits that exhibit discontinuous variation. what kind of traits are these?

5 0

Discontinuous variation is when a trait is seen in a population in two or more different forms and there is no continuation along a gradient. A good example that Mendel studied is flower color. The flowers were either white or purple. There was no in between color. This is caused by an allele for purple or a lack of an allele for purple, which produces no pigment, or white.

Answer:

All the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

Explanation:

Given

Tallness ( T) is dominant to dwarfness (t)

Red (R) flower color is dominant to white (r)

It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance

Genotype of dwarf red snapdragon is RRtt

Genotype of a plant homozygous for tallness and white flowers is rrTT

The punnet square representing the cross between RRtt and rrTT is as given below-

Rt Rt Rt Rt

rT RrTt RrTt RrTt RrTt

Thus all the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

The body felt cool to the touch. The thermometer gave a reading of 70˚F. No rigor mortis was evident, but permanent livor mortis

BigorU [14]

Answer:

Basically enzyme activities are affected by drop in temperature. in additions the corpse was cool to touch.Therefore this explains while there was no bloating or bacteria activity since the decomposing bacteria enzymes were inactive because of the cold temperature.

Consequently, if the Livor mortis (lividity) is +8hrs 0-4days, evidently the corpse must have been refrigerated after livor mortis sets in, with the decomposition slowed down by the cold environment.

Notes: Algor mortis is 26.8hrs, and there was no algor mortis.
