What is the difference between a monohybrid cross and a dihybrid cross?

Answers

Answer 1
Answer: A monohybrid cross only involves one trait, for example "shape". A dihybrid cross involves two traits, for example "shape " and "height".
Answer 2
Answer:

Final answer:

A monohybrid cross involves the study of one trait at a time, while a dihybrid cross involves the study of two traits simultaneously.

Explanation:

A monohybrid cross is a genetic cross that involves the study of one trait at a time. It is focused on analyzing the inheritance of only one pair of alleles. In contrast, a dihybrid cross is a genetic cross that involves the study of two traits simultaneously. It is used to determine the patterns of inheritance for two different gene pairs.

For example, let's consider a monohybrid cross involving flower color in pea plants. If we cross a purebred yellow flowered pea plant (YY) with a purebred green flowered pea plant (yy), the resulting offspring will all have yellow flowers (Yy). In a dihybrid cross, we would consider two traits, such as flower color and seed shape. We could cross a purebred yellow, round-seeded plant (YYRR) with a purebred green, wrinkled-seeded plant (yyrr), resulting in offspring with yellow, round seeds (YyRr).

In summary, the main difference between a monohybrid cross and a dihybrid cross is that a monohybrid cross focuses on one pair of alleles for one trait, while a dihybrid cross focuses on two pairs of alleles for two different traits.

A plant leaf shows veins arising from a central thick vein to form a complicated network. Which type of venation does this plant exhibit? A. ParallelB. CrisscrossC. Reticulated

Answers

The type of venation which does the plant exhibit that the leaf shows veins arising from a central thick vein to form a complicated network is the (C.) Reticulated venation.
In reticulated venation, the veins here are arranged in a net-like pattern and are all interconnected. It is also the most common type of venation.

Answer:

C. Reticulated

Explanation:

In reticulated venation there is a central thick vein in the leaf and from there other little veins that form a net flow to the different parts of the leaf, that is called REticulated venation, it often happens that the central vein is located in the middle of the leaf and are easily spotted because that central vein creates a leaf that is two very similar halfs.

Explanation:

if there were no suppression of dna replication between meiotic divisions but cytokinesis proceeded normally, what is the most likely outcome of meiosis?

Answers

The answer is 4 diploid cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no suppression of DNA replication, then meiosis I would produce two diploid cells, and after meiosis II there will be four diploid cells.
