Answer:
100%
Explanation:
Assuming the gene for polydactyly is represented by P. Normal finger will be represented by p.
A woman that is homozygous for polydactyly trait will have genotype PP while a man with normal 5 fingers and toes will have the genotype pp (since P is dominant over p).
PP x pp = Pp, Pp, Pp and Pp.
All the offspring will have the genotype Pp and since P is dominant over p, it means all the offspring will have polydactyly trait.
<em>Hence, the percentage of the offspring of the couple that would be expected to be polydactyly is 100%</em>
Answer:
To strengthen the ecosystem
They need both aspects for photosynthesis and respiration
Abiotic things can be used by plants to for soil fertility
Explanation:
Living organisms cannot exist without the nonliving aspects of the environment. For example: air, water, and sunlight, which are all nonliving, are all essential to living organisms. Both nonliving and living things make up an ecosystem.
Answer: D. About half of the offspring will have purple flowers, and about half of the offspring will
have white flowers,
Explanation: Purple flower is dominant over white flower, therefore a cross between Pw and ww will produce four offsprings, fifty percent of which will have purple flowers and the other fifty percent will have white flowers. The genotypes of the offsprings are Pw and ww. Pw will manifest outwardly as purple flowers while ww will manifest outwardly as white flowers.
