1. An underdeveloped DNA molecule would result in mutations. On the genetic level, this could mean entire traits are deleted or that an early stop occurs in transcription, which could cut off parts of instructions.

2. Genetic code is the nucleotide sequence of a gene while the gene expression is how these sequences are used to make functioning amino acids and proteins to create DNA.

3. In each cell itself there are roughly 42 million proteins.

In squash, yellow seeds are dominant over green seeds. If two heterozygous yellow seed squash were crossed, what are the genotyp
Umnica [9.8K]

Answer:

The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1  and phenotype proportion 3:1

Explanation:

The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.

For the characteristic "seed color" the green color would be G and yellow represented as g.

At the cross of two heterozygous squashs:

- Parents: Gg X Gg

- <u>Punnett's Square</u>:

Alleles    G         g

G           GG       Gg

g           Gg        gg

Offspring:

  • A pumpkin of green seeds GG (25%)
  • Two pumpkins of green heterozygous seeds Gg (50%)
  • One pumpkin of yellow seeds gg (25%)

Genotype proportion 1:2:1

Phenotype proportion 3:1

FinnZ [79.3K]

Answer:

d. cerebellum.

Explanation:

The cerebellum, which is part of the hindbrain, is a small structure made of a covering of white cortex found under the hemispheres of the cerebral cortex. The cerebellum plays a major role in the control and coordination of all physical movements such as balance, control, etc, that has to deal with smooth and balanced activities of the muscle.  

A damage to the cerebellum would most likely lead to impaired motor coordination, staggering, inability to judge distance or when to stop.

kicyunya [14]

Answer: Option A Anaphase

Explanation:

Anaphase is one of the stages that takes place during cell division either mitotic or meiotic. Anaphase in mitosis and meiosis II involves the separation of the two sister chromatids at the centromere and then the each migrates to opposite ends of the pole which is aided by the spindle assembly. Anaphase in meiosis I involves the separation of a pair of homologous chromosomes to opposite ends of the poles.
