Answer:

The punnet square can be completed as follows:

C C

A AC AC

The results from the punnet square show that all of the offsprings form will be agouti as agouti is the dominant trait. However, the genotype of the offspring will be heterozygous carrying the alleles AC.

A dominant trait is the trait which arises due to a dominant allele. The dominant allele masks the effect of the recessive allele.

A heterozygous genotype occurs when the alleles of a gene are different.

The early Paleocene world was slightly ____ then the proceeding Cretaceous period

zavuch27 [327]

The answer is 'cooler'. The Cretaceous Period was relatively warm and was experiencing global warming. However, a cooling trend was evident towards the end of the Cretaceous. The Paleocene followed the meteorite impact that resulted in the extinction of most of the dinosaurs. It is thought that dust particles in the atmosphere resulted in cooling during the early Paleocene.

According to the Punnett Square shown above

Alexxandr [17]

Answer:

C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.

Explanation:

Note that the brown eyes is the dominant trait, denoted by B, while blue eyes is the recessive trait, denoted by b. In all cases of the Punnett square, if there is a dominant and recessive trait, the dominant trait will always come out on top.

The given Punnett square:

$\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right]$

Note that there are 3 options (BB, Bb, Bb) respectively, in which there is the dominant trait B (brown eyes). Only in one case is there only the recessive trait b (blue eyes), or a 1/4 chance of obtaining blue eyes. Therefore, there is a 3/4 chance of obtaining a brown eye:

C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.

In a nucleotide, which would change based on the genetic code of the organism?

Setler79 [48]

Answer:

The correct answer is nitrogen base

Explanation:

The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.

As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.

In simple words change in single nitrogen base of a codon will change the entire codon.
