When Mendel crossed a true-breeding short plant with a true-breeding tall plant all the offspring were tall. Which term describe
max2010maxim [7]

Hi!


The answer would be: Dominant


<h3>Explanation</h3>

A cross between a true breeding short plant (homozygous for short, suppose tt), and a cross between a true breeding tall plant (homozygous for tallness, suppose TT) would result in all the offspring being heterozygous for the traits, meaning they would each have an allele of shortness (t) and an allele of tallness (T).

Considering the offspring were all tall, we understand that the allele for tallness must have been dominant over the allele for shortness to present itself over it. Hence, the term describing the gene for tallness would be dominant, and the term describing the gene for shortness would be recessive.


Hope this helps!

 What chromosome is a sex-linked trait located on?
Gelneren [198K]

Answer:

Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome.

As a plant grows, new root hair cells are formed from unspecialised cells.
Marina86 [1]

Answer:

Root hairs appear in the root maturation zone and differentiate from unspecialised cells called trichoblasts.

Explanation:

Root hair arises as a small protrusion surrounded by a cell wall, they are found in the piliferous area; they can originate in unspecialised epidermal cells, in some called trichoblasts. The bump begins to elongate and moves away from the epidermis, forming root hair. The root hairs as they lengthen, it is seen that their content shows a polarized distribution, the apical part is constituted mainly by vesicles secreted by the Golgi apparatus that contain the precursors of the cell wall that are to be released by exocytosis. Trichoblasts can be arranged in different ways, there are roots where any of the cells that are part of the rhizodermis can give rise to a root hair. In other roots, trichoblasts and atricoblasts have been seen to be distinguished alternately along a row of cells.
