Pea seed color exists as green or yellow. We might say that "yellow" is an example of a (an)_ for seed color
LiRa [457]

Answer:

b. allele

Explanation:

An allele is a variant form of a gene. In this problem, there is one gene (that determines seed color) with two possible alleles (green and yellow).

<u>The other options are wrong because:</u>

The genotype is the combination of alleles an individual has.

The karyotype is an individual's collection of chromosomes, paired and ordered.

A homozygote individual has the same alleles for a particular gene.

A heterozygote individual has different alleles for a particular gene.

adoni [48]

Answer:

B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.

Knowing what we know about the link between genetics, environment and intelligence, what would be your expectations if you were
Vesnalui [34]

Answer:

I would expect them to perform similar.

Explanation:

Studies suggest that intelligence has a genetic component and can, in part, be passed from parent to child - but not only that. There are outer components that contribute to the formation of intelligent individuals. Better nutrition and more access to education would be possible explanations for the progressive increase in intelligence test scores over time.

Homozygous twins are those that are mainly characterized by similarity between individuals. These twins are formed from the same zygote, ie after the fertilization process. Because of this characteristic, they have the same genetic heritage and are therefore considered identical.

As the homozygous twins in their classroom have the same genetic heritage and attend the same environment, we can conclude that their intelligence is influenced by the same factors. For this reason, a teacher who taught these two brothers might have expectations that they would perform similarly in the classroom.
