In humans, a type of blindness is due to a dominant allele (B). Normal vision is the result of a
barxatty [35]

Answer:

Yes, a child with normal vision who does not suffer from headaches can be produced.

The probability of producing such child from this cross is 1/2 or 50%

Explanation:

This question involves two distinct genes in humans. One coding for blindness and the other for Migraine headaches. The alleles for blindness (B) and Migraine (M) are dominant over the alleles for normal vision (b) and no Migraine (m).

According to the question, a male who is heterozygous for blindness and does not suffer from migraines will have the genotype; Bbmm while a female who

has normal vision and does not suffer from migraines will have genotype; bbmm. If these two parents are crossed, the following genotypes of gametes will be produced by each parent:

Bbmm- Bm, Bm, bm and bm

bbmm- bm, bm, bm, and bm

Using these gametes to construct a punnet square (see attached image), the following offsprings with genotypes; Bbmm and bbmm in the ratio 1:1 will be produced.

Bbmm (8/16) are offsprings with blindness and have no Migraine headache

bbmm (8/16) are offsprings with normal vision and have no migraine headache

Hence, this cross can produce a child with normal vision who does not suffer from headaches (bbmm). Also, the probability of producing such child is 8/16 or 1/2.

How the needs of a group of people may affect what scientists choose to study.
nignag [31]

Explanation:

It’s an important question because the road to a successful career in science – as with technology, engineering and mathematics, the other STEM fields – can be challenging, often requiring a Ph.D. or other postgraduate training. And once in their fields, there can be political and economic pressures with which to contend. The Bureau of Labor Statistics projects workforce shortfalls for many science fields, though the projected needs differ across the life, physical and natural sciences.

Why are antibiotics unhelpful for treating the common cold apex?
gogolik [260]
Common colds are caused by viruses and antibiotics only work in bacteria. Antibiotics work by targeting the different replication processes and functional characteristics of bacteria. Virus on the other hand are only active once they have invaded something to use as a host. Therefore it is more difficult to target the mechanisms of viruses because they are usually dormant and have different organelles than of bacteria.
