Answer:
GG, Gg, Gg, gg
Homozygous green – GG
Heterozygous green – Gg
Homozygous yellow - gg
Explanation:
It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.
The genotype of the true breeding Green plant is “GG”
The genotype of the true-breeding yellow plant is “gg”
F1 generation cross
GG * gg
Offspring produced from F1 generation are – Gg, Gg, Gg, Gg
In f2 generation offspring of F1 generation are crossed among each other.
So the offspring produced in F2 generation are
Gg * Gg
GG, Gg, Gg, gg
Homozygous green – GG
Heterozygous green – Gg
Homozygous yellow - gg
Answer: Genetics and Pressures
Explanation:
For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.
Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.
Answer:
a) releases neurotransmitter that binds to the effector cell
The correct answer is the anterior pituitary gland.
The Anterior Pituitary Gland is best described as the glandular, anterior lobe that together with the posterior lobe makes up the pituitary gland. The anterior pituitary regulates numerous physiological tactics inclusive of strain, increase, duplicate and lactation.The proper functioning of the anterior pituitary and of the organs, it is responsible for regulation, it can often be ascertained thru blood checks that degree hormone stages.
The correct answer is C. Genetic analysis
Explanation:
In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
