The genotype for people who do not taste PTC?​

Biology
1 answer:
DerKrebs [107]3 years ago
4 0

Answer:

Virtually all non-tasters (dd) cannot taste PTC, while homozygous tasters (TT) occasionally report an inability or weak ability to taste the chemical. The heterozygous genotype (Tt) has the "leakiest" phenotype as reduced or absent tasting ability is relatively common. This is formally called a heterozygous effect.

Explain why biodiversity in an ecosystem is important?
rusak2 [61]

Answer:

It is important because we need many different types of animals. Food chains are made up of many different links, and if there are fewer links, this will lead to animals not being able to feed. Biodiversity boosts the ecosystem and leads to an ecosystem that is self sustaining and able to produce things for people.

- Start with the P generation with the following genotypes (AA x aa). Based on classical Mendelian inheritance, how will a cross
nexus9112 [7]

Answer:

<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring  will all be heterozygous and increase chances of future variation.</em>

Explanation:

The cross for the offsrings that will be produced by F1 generation is shown below:

         a          a

A      Aa       Aa

A      Aa        Aa

As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.

A cross between the F1 generation will give the following results:

         A          a

A      AA      Aa

a       Aa      aa

This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
LiRa [457]

The right answer is inversion.

Inversion is a genetic mutation characterized by the end-to-end reversal of a portion of chromatid on a chromosome.

In other words, it is a double break then it is replaced after rotation of 180 ° of a chromosome segment (backward insertion).

We distinguish :

Paracentric inversions:  The centromere in the chromosome is not included in the inversion.

Pericentric inversions:  The centromere is included in the inversion which transforms a metacentric chromosome into an acrocentric chromosome.
