Answer:
Organism
Explanation:
flowers and pure-breeding short pea plants with white flowers. The alleles for
a tall height and purple flowers were dominant. This cross is written as
A. TtPpx TtPp
в. TTppx ttPP
с. Ttppx TtPP
D. TTPPx ttpp
Answer:
The correct answer is - ttPP × TTpp
Explanation:
Answer:
D
Explanation:
He bred two true-breeding strains initially. That means the alleles were homozygous for each gene.
Let's use Tt to represent the height allele: T means tall, t means short; the dominant allele gets the capital letter.
Let's use Pp to represent the flower color allele: P means purple, p means white.
A pure-breeding tall, purple plant would be TTPP.
A pure-breeding short, white plant would be ttpp.
So the cross is D. TTPP x ttpp.

The transfer of genetic information that occurs between the two lizard populations above is known as
Answer:
The transfer of genetic information that occurs between the two lizard populations is known as GENE FLOW.
Explanation:
The options attached to this question are given below:
A. Genetic recombination.
B. Gene flow.
C. Genetic drift.
D. Natural selection.
Gene flow refers to the transfer of genetic variations from one population to another of the same species. The rate of gene flow between two populations may be low or high. When the rate of gene flow is high the populations are considered to be a single population.
In the scenario given in this question, there is a flow of large neck frill genetic trait from the parent lizards in Island B to the offspring that result from sexual relationship between the lizards from both islands.
