Answer:

The correct answer would be c. haploid and are made when haploid spores undergo mitosis.

Angiosperms are flowering plants.

Pollen is formed in the anther of the flowering plant. Pollen is haploid in nature as they are formed from the meiotic division of microspore mother cell. This process is termed as microsporogenesis.

Later, these microspores develop into the microgametes by the process termed as microgametogenesis. Under this process, the microspore undergoes mitotic division and produce two haploid nuclei. One nucleus is termed as the vegetative nucleus and another is termed as the generative cell.

malfutka [58]

Answer:

Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance

Explanation:

Let the allele for floppy ears be "F" and the allele for straight ears be "f"

And Let the allele for black coat color be "B" and the color for white coat color be "b"

Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)

The 16 offspring have genotype FfBb

Phenotype of 16 offspring is Floppy ears and grey coat

Ff represents the floppy ear , thus "F" is dominant over "f"

Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.

Hence, option E is correct
