Answer: - Predict an unknown genotype of a purebred dominant plant.
Explanation:
The genetic make up of the organism is called as the genotype. It describes the form of genes or allelic forms present in the organism. A test cross is used to determine the genotype of the organism. In this cross the organism with the unknown genotype is done with that of the organism with the known genotype. It also determines the fact that the organism is either homozygous dominant or hetrozygous.
On the basis of the above description, Predict an unknown genotype of a purebred dominant plant.
Answer:
Option C
Explanation:
Brent will opt to work with an individual who has the desired characteristics to meet the work requirement and could also go along with efficient team building. Thus, in case if both Ken and Darwin have similar characteristics, then Brent would prefer to work with both the person irrespective of their color. Physical characteristics will not impact Brent decision for choosing one amongst the two.
Hence, option C is correct
Fewer. more expose to sun could kill plants off.
<u>Answer:</u>
The correct answer option is D. Carry nerve impulses from the brain to skin, glands, and muscles
<u>Explanation:</u>
Motor neurons carry signals out of the Central Nervous System (CNS).
These motor neurons have long extensions called axons which spread from the CNS to the muscles that connect with the innervate.
The information from the brain to the muscles and other glands is sent in the form of electrical impulses via the spinal cord.
Answer: Rare X-linked recessive
Explanation:
In humans our biological sex-determination is based on a pair of sex chromosomes namely, XX in females, XY in males. The genes on our X chromosome are X-linked. and have special patterns of inheritance due to their presence in contrasting numbers in males (XY, 1 X chromosome) and females (XX, 2 X chromosomes); thus they are more common in genetic males.
The observed trait is X-linked, and given that only half the sons are affected, the trait is recessive and carried by the heterozygous mother -heterozygous alleles are two variants of the allele at the same gene locus. The Y chromosome inherited from the father does not carry the gene, thus there is no normal copy available. The incidence for its inheritance is at 50% as the mother has two X hromosomes, one normal, and one carrying the trait.
