Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed
Juli2301 [7.4K]

Answer:

The F1 progeny is completely heterozygous for the <em>loci</em> of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids

Explanation:

An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single <em>locus</em>, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing​).

Andre45 [30]

Answer: The answer is C- Gamma amino butyric acid and glycine are excitatory neurotransmitters.

Explanation:

This is because Gamma amino butyric acid (GABA) and glycine are known to be inhibitory neurotransmitters in the central nervous system. They are both amino acids, they act as inhibitory neurotransmitters by blocking nerve impulses. Inhibitory neurotransmitters are known to decrease neuron's action potential.

2. Introduce one of the four new rat species to another island and describe one challenge it would encounter and one success as
snow_tiger [21]

Answer:

Challenge : Competition form other species.

Success :  Adaptation and colonisation.

Explanation:

  • Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge.
  • Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.
