Answer:

C. The female cone releases its seeds and new sporophytes grow.

Explanation:

During life cycle of conifers, pollen grain serves as male gametophyte that pollinate the female gametophyte. The female gametophyte is present in female cone and bears egg in archegonia. Fertilization and post fertilization events lead to seed development in female cone. The seeds are released and seed germination leads to formation of a new sporophyte.

n mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele (coats are n
nexus9112 [7]

Answer:

The probability of getting a dwarf and pink female is 1/2

Explanation:

In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.

A dwarf female from a pure line will have Xd Xd where d represent the  recessive trait and the female is also brownish (pp).

A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).

            Xd             Xd                            Xp          Xp

XD       XDXd        XDXd             XP    XPXp     XPXp    F1 generation

Y           XdY           XdY                Y     XpY        XpY

P        XDXd   x    XdY                        XPXp    x    XpY

           XD         Xd                               XP              Xp

Xd     XDXd    <u>XdXd</u>                  Xp    <u>XPXp</u>         XpXp         F2 generation

Y        XDY        XdY                   Y       XPY          XpY

The probability of getting a dwarf and pink female is 1/2
