Plants make their own food by a process called Photosynthesis. ... Photosynthesis is done with the help of carbon-dioxide, water, and sunlight. The end products of photosynthesis are oxygen, which the plants release, and carbohydrates, which become the plants' source of energy
The main difference between population and community is that a population is a group of individuals of a particular species living in a particular ecosystem at a particular time whereas a community is a collection of populations living in a particular ecosystem at a particular time.
Answer:
Complex Inheritance: (inherited) traits that have a genetic component that does not follow strict Mendelian inheritance. May involve the interaction of two or more genes or gene-environment interactions. ( HGPIA)
Explanation:
Answer:
PPTt
Explanation:
Let the gene for flower colour be denoted by P. P is the dominant allele and produces purple colour, p is the recessive allele and produces the recessive colour. Let the gene for stem height be denoted by T. T is the dominant allele and produces tall stem, t is the recessive allele and produces short stem.
A test cross was done which means that one of the parents was homozygous recessive for both the traits i.e. pptt
In the progeny all the flowers had purple colour which is only possible if the test parent was homozygous dominant for the trait i.e. it was PP
PP x pp :
P P
p Pp Pp
p Pp Pp
As evident, all the flowers will have Pp genotype and hence purple colour.
In the progeny, around half of the flowers had tall stems and half had short stems. This is only possible if the test parent was heterozygous for the trait i.e. it was Tt
Tt X tt :
T t
t Tt tt
t Tt tt
As evident, half plants have Tt genotype so they will have tall stems. Half of them have tt genotype hence will have short stems.
Hence, combining the genotype for two traits we obtain the genotype PPTt of the original test pea plant.
