consuming high levels of provitamin a carotenoids, which come from plant sources, does not lead to vitamin a toxicity.

Feliz [49]

Consuming high levels of pro vitamin A carotenoid, which come from plant sources, does not lead to vitamin A toxicity. This statement is true.

Vitamin A is obtained mainly from the food products we eat, but it is also synthesized in our body via pro vitamin A carotenoids like beta-carotene. When high amounts of pro vitamin A carotene are consumed in the diet of a person they are converted very slowly and naturally in our body into vitamin A in the intestine.

Vitamin A has many benefits including defense from pathogens, strengthening immune system, improving vision, and also improving overall growth and development of the body etc.

What is the probability that the offspring will have purple flowers?; What is the phenotypic ratio for the purple flowers?; What

Luda [366]

The probability that the offspring will have purple flowers is 50% chance Let's go ahead and assume that:

The allele A corresponds to the color of flowers.

As a result, A would stand in for the alternate white hue and represent the dominating purple color.

According to the aforementioned hypotheses, a white flower would have the genotype aa while a heterozygous purple blossom would have the genotype Aa.

Now let's connect the two flowers:

Aa x aa

Aa Aa aa aa

The genotypes, phenotypes, and odds of the offspring would be as follows based on the cross's outcomes:

Purple color, Aa; 1/2

white flower color, aa, 1/2

In other words, there is a 50% chance that the cross will result in offspring with the flower colors purple (genotype, Aa) and white (genotype, aa).
