Two individuals that are heterozygous for tongue rolling mate. What are the predicted genotypic and phenotypic ratios for this c
slamgirl [31]

Answer:

Genotypic ratio = 1:2:1

Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller

Explanation:

This question involves a gene coding for the ability to roll the tongue or not in humans. The allele for tongue rolling (R) is dominant over the allele for non-tongue rolling (r).

According to this question, two individuals that are heterozygous for tongue rolling mate i.e. Rr × Rr. The proportion of offsprings that will be likely produced from this cross will be: RR, Rr, Rr, and rr.

- Offsprings with RR, Rr, Rr are tongue rollers

- Offsprings with 'rr' are non-tongue rollers.

Hence, the predicted genotypic and phenotypic ratio are as follows:

Genotypic ratio = 1 RR :2Rr :1rr

Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller

VikaD [51]

Plant root hairs help to absorb carbon dioxide from the soil.

Root hair cells

Plants absorb water from the soil by osmosis. They take up mineral ions by active transport against a concentration gradient. Root hair cells are well-suited for absorbing water and mineral ions because of their large surface area and high absorptive capacity.

It also contains many mitochondria, which release energy from glucose during respiration to provide the energy needed for active transport.

To know more about mitochondria,
