Answer: There will be one homozygous straight wing, two heterozygous straight wings, and one homozygous curly wing.
Explanation: A true breeding pair means that both parents are heterozygous (Ww). Set up a Punnett square with two Ww parents. The offspring will be 1 WW (homozygous straight), 2 Ww (heterozygous straight), and 1 ww (homozygous curly).
The bone that's most commonly used to determine the height of the deceased is the femur (although the humerus can also be used). <span>The femur is measured in cm and the calculations may very according to the gender of the deceased and can be accurate within 5 cm.
The femur is a long bone that is hard and, therefore, can keep its integrity longer. As well as it is a bone that generally is proportional to the body.</span>
Answer:
Bacteria that are non-controlled or destroyed by antibiotics are antibiotic-resistant bacteria. In the presence of an antibiotic, they will live and even develop. At least certain antibiotics can become immune to most infection-causing bacteria.
Explanation:
Some bacteria are immune to such antibiotics naturally. In most species found within the human digestive system, for example, benzylpenicillin has very little impact.
In this case, the black body colour is the dominant one. The white dog is homozygous recessive.
As the cross between the black female 2 and the white male results in all black pups. This means that the all the offsprings are heterozygotes and the Female 1 is homozygous recessive having a BB phenotype (where B codes for dominant allele).
As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).
