Answer:
False, they can have recessive phenotype
Explanation:
A phenotype is a viable characteristic an individual presents as a consequence of the interaction between its environment and its genotype.
This doesn’t necessarily means that the individual’s aleles are both dominant (homozygotes), they could have one dominant and one recessive gen (heterozygotes), meaning that, if the another parent is homozygote with both recessive aleles the offspring could heritage homozygote recessive aleles that will result in a recessive phenotype.
You can observe in the image I added a punnet square that exemplifies the scenario. You can see that the offspring has 1/2 probability to have recessive phenotype.
I hope you find this information useful and interesting! Good luck!
Irregular stream flow which causes swirling of water in a specific area and localized erosion causes a deeper section known as a deneduation.
<h3>
What is deneduation?</h3>
The processes of erosion, leaching, stripping, and diminishing the mainland as a result of material removal from higher to lower locations such valleys, river valleys, lakes, and oceans with a permanent filling of low lands are together referred to as denudation.
The elevation and relief of landforms and landscapes on Earth's surface by flowing water, ice, wind, and waves.

The answers are:
<span>a. -/b+
</span><span>d. b/b+</span>
b+ - the allele for normal bristles
b - the allele for bent pristles
Monosomic means there is only one instead of two alleles in a gene locus.
So, the parents' genotypes are:
<span>monosomic bent bristles: -/b
</span><span>diploid normal bristles: b+/b+
</span><span>The following cross is conducted of true-breeding adult flies:
Parents' phenotype: monosomic bent bristles x diploid normal bristles
Parents' genotype: -/b x b+/b+
F1 generation: -/b+ -/b+ b/b+ b/b+</span>
