In humans, a type of blindness is due to a dominant allele; normal vision is the result of a recessive allele. Migraine headache
yan [13]

Answer:

Yes.

Probability of such child = 1/2 or 50%

Explanation:

According to the question, below are the genotypes and phenotypes possibilities:

aa = normal vision & no headache

Aa = normal vision & no headache

AA = blindness & headache

                                                                      Male                       Female

                                                                        Aa                            aa

Possible genotypes of progeny:            Aa        Aa           aa         aa

So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.

Mathematical expression is as under:

2/4 = 1/2 that means 50% progeny.

What does this article reveal about the role Black inventors have played in America's history? Explain your answer.
cupoosta [38]

Answer:

The article revealed the fact that Black inventors have always played an active role in inventing new things in America. In the 18th and 19th centuries they were denied the right to patent their inventions because of their status as slaves. This has changed for the better in present times as many Black inventors are being granted patent rights.

Explanation:

The article, "America’s always had black inventors – even when the patent system explicitly excluded them", by Shontavia Johnson, explained the active role that Black Americans, both free and slaves played in inventing things in the United Slaves. The article explained that although the patent rights signed into the constitution in 1787 was written in a neutral tone, it did not change the fact that black inventors were actually denied patent rights.

This segregation affected people like Henry Boyd, Ned, Benjamin Montgomery among others. In recent times, this segregation has significantly been curbed as many Black inventors are now owners of patents. An example is Lonnie Johnson, inventor of the Water Gun and owner of more than 80 patents.

What could happen to the reproductive process of mosses during a drought? The flagellated sperm would not be able to swim to the
Wittaler [7]
The answer is <span>The flagellated sperm would not be able to swim to the eggs for fertilization.

</span><span>Their life cycle of mosses has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. The zygote grows into diploid sporophyte which produces haploid spores. The spores grow into gametophyte and the cycle begins again.
</span>Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.
