Answer:
The offsprings will express the dominant trait of the male parent.
To understand this, lets make a punnet square. Let's consider the dominant alleles of the male parent to be DD and the recessive alleles of the female parent to be dd.
d d
D Dd Dd
D Dd Dd
The results from the punnet square depict that all the offsprings will have a heterozygous genotype but ad the dominant allele masks the effect of the recessive allele hence, the offsprings will show the phenotype of the dominant allele.
Answer:
They are killed by predators for energy
