Answer:
Phenotype
Explanation:
Genotype would be something like homozygous recessive, heterozygous dominant, HH, Hh, hh (etc). It describes the genetical pattern in offspring.
Phenotype is the physical description, such as black fur, brown fur, long ears, short ears, indigo petals, white petals, (etc).
Answer:
Well, you need an egg and a sperm to reproduce
So neither are correct you need both
Stop copying and start studying
<span>Since the pea plans are heterozygous they contain one dominant and one recessive allele. When you extrapolate this out we find that 25% of the plants will be homozygous dominant, 50% will be heterozygous, and 25% will be homozygous recessive. So 75% of the plans will have round peas.</span>
Option 2 is the only option that makes sense. It is asking about what the nervous system (the brain) sent to the circulatory system (blood vessels). The legs would need more blood flow in order to keep the leg muscles oxygenated.
Option 1 is incorrect because if there is less blood flow to the legs, the muscles would tense up and you would not be able to run.
Option 3 is incorrect because it says the heart sends signals to the brain, which is not what the question was asking.
Option 4 is incorrect because the heart would start beating faster as your run a marathon in order to keep the body properly oxygenated.
