kow [346]
Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities.  In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.

In mice, the ability to run normally is a dominant trait. Mice with this trait are called running mice (R). The recessive trait
BlackZzzverrR [31]

Answer:

Parental genotypes: RrBb, RRBB

Offspring phenotype: Running and black hair

Explanation:

Given, Running (R) is dominant over waltzing (r)

Black hair (B) is dominant over brown hair (b)

Parent 1: Heterozygous running, heterozygous black = RrBb

Parent 2: Homozygous running, homozygous black = RRBB

When they mate ( RrBb X RRBB ) :

Gametes produced by RrBb = RB, Rb, rB, rb

Gametes produced by RRBB = RB

Offspring:

        RB          Rb         rB        rb

RB   RRBB    RRBb    RrBB    RrBb

All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.
