The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.
<h3>How to calculate genotype of a cross?</h3>
According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.
If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:
This shows that the probability of the offspring of a heterozygous father and homzygous mother having five fingers is ½ (50%).

Answer:
C) maleness results from the minimal presence of one Y chromosome
Explanation:
- From the given question, it can be clearly observed that in males irrespective of whichever syndrome they have a Y chromosome is always present whereas in females Y chromosome is not present.
- Hence, one cal conclude that whenever the Y chromosome is present the individual acquires male characters.
- The Y chromosome whenever present produces the hormones that leads to maleness, and the number of Y chromosomes in males can also be more than one such as in case of XYY Klinefelter syndrome.
The answer is; D
The simplicity of the prokaryote bacteria cells can depict the origin of life. It is simply composed of microscopic unit enclosed in a plasma membrane and cell wall. The inside contains a small DNA molecule, ribosomes and cytoplasm (they have no organelles). They have been around for 2 billion years on earth before other organisms evolved from them.
