Answer:

<h2>Genotypes of parents are Rr and rr.</h2><h2 />

Explanation:

A homozygous fox would have either two dominant alleles (RR) or two recessive alleles (rr).  

A heterozygous fox would have a mix of both one dominant allele and one recessive allele (Rr).

However, a heterozygous fox can only be red, as the (Rr) combination will make it so that the dominant red coat trait will rule over the recessive allele.

(a).  as given that f 1 generation are 4 red and 3 white , so RED coat can not be homozygous dominant , So red coat will be Rr (heterozygous dominant).

(b). silver coat is recessive homozygous , rr

(c).  genotypes of offspring  Rr, Rr, rr, rr.

(d) yes

(e) yes

Which molecules of the adaptive defense system provide humoral immunity by circulating freely in the blood and lymph, where they
alisha [4.7K]

Answer:

Adaptive immune defense system consists of lymphocytes like B-lymphocytes and T- lymphocytes. B-lymphocytes provides humoral immunity while T- lymphocytes provide cell-mediated immunity to the body.

99% of lymphocytes circulate freely in the blood and lymph. B lymphocytes differentiate into plasma B cells and B memory cells when interact with antigen presented by T helper cells.  

Then plasma cells secrete antibodies in the circulation which binds to extracellular antigens through antigen-binding site. Then the bounded antigen is recognized by receptors present on phagocytic cells. This receptor binds the Fc region of antigen bounded antibody and destroy the antigen by phagocytosis.
