What do you know about the Punnett Square? (Don’t research it or you will not get credit for this question.)
Ivanshal [37]

Answer:

Well it says not to research so here's a brief definition: A punnet square is a diagram that shows the genotypes of a cross and helps predict the probability of having certain genotypes.

Explanation:

Heres some words to know

-Dominant

-Recessive

-Allele

-Mendel's law of Heredity

Let me know if you want more explanation on these :)

In a humoral or antibody-mediated immune response, specific B cells are stimulated by Helper T cells to help transform into plas
steposvetlana [31]

Answer:

An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).

Explanation:

The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.

The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.

<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.

!!Help!! In dogs, the gene for fur color has two alleles. The dominant allele (F) codes for grey fur and the recessive allele (f
tatiyna

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.
