ValentinkaMS [17]

Answer:

All the offsprings will be black-furred (Bb)

Explanation:

This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.

According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:

BB - B only

bb - b only

Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:

Bb, Bb, Bb, Bb

All Bb (heterozygous) means that all of the offsprings will be black-furred.

Goshia [24]
After fertilization of the ovule, the megaspore develops into the food supply of the mature seed.
After fertilization of the ovule, the <em />integument develops into the seed coat.
After fertilization of the ovule, the fertilized egg develops into the embryo of the mature seed. 

The ovule contains the female reproductive cells of the seed plants and when fertilized, it produces the seed. Ovules contain megasporocytes, cells that produce megaspores through cell division. An integument is a layer that protects and surrounds the ovule. After fertilization, the integument protects and surrounds the seed. After fertilization, the ovule contains a diploid zygote which develops into an embryo.
