Answer:
The percent chance that the offspring will have a single comb is 
%
Explanation:
Given,
The allele for single comb represented as "a" is recessive to the allele for pea comb represented as "A"
Genotype of male - Aa
Genotype of female - Aa
Gamete of Male - A, a
Gamete of female - A, a
Cross between Aa and Aa will produce
AA, Aa, Aa, aa
Thus, out of four offspring only one has "aa" genotype and hence this individual will express the recessive trait i,e aa
The percent chance that the offspring will have a single comb is
%
Answer:
Convergent Evolution
Explanation:
Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.
An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.
Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate
.
The right options are;
are disease-causing microorganisms
can be fatal
A pathogens is any substance or organism especially microorganisms that are capable of causing diseases. Pathogens include; bacteria, viruses, protozoa or fungi. Microorganisms are not considered to be pathogenic until they have reached a population size that is large enough to cause disease. Pathogens can be fatal and can be treated. Pathogens are diverse and they occupy essentially every environment.
Answer:
Genetic monotony is the result of asexual reproduction which generation after generation exactly identical progeny develops.
Explanation:
The process of sexual reproduction involves two parents, each of hem contributing one gamete. Gametes are produced by a process called meiosis, which starts by the duplication of the chromosomes, followed by two rounds of cell divisions and halving of the chromosome number. Gametes have half the chromosome number of other adult cells of an organism.
