Explanation:
Option D is the correct option.
Photosynthesis provides materials for cellular respiration; phitosynthesis produces sugar and oxygen to use to make more CO² and ATP
Answer:
This is an example of recessive epistasis.
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in <em>different loci in the same chromosome</em>. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
In recessive epistasis, the proportion is 9:3:4.
Answer:
100
Explanation:
If crossing DD ×dd, then off springs are 4 Dd. so all carry dominant D.
