Answer:
This is Law of Dominance.
Explanation:
- On crossing pure bred pea plants having one trait of a character with pure bred plants having a different trait of the same character , Mendel noticed that all the plants in the first filial generation were having only one trait though they received the factor for other trait.
- However, when he allowed these plants of first filial generation to pollinate themselves, the other trait also appeared in some plants of second filial generation.
- And thus the law of dominance was framed, which stated that, characters are controlled by discrete units called factors, these factors occur in pair and in a dissimilar pair of character one factor dominates and the other fails to appear.
Answer:
in dogs there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are mated. what are the possible genotypes and phenotypes of their offspring and the percent of chance for each?
Dd x Dd = DD, Dd, Dd, and dd
3:1 genotype
phenotype shows that there is 3 dominant gene for normal hearing while 1 for deafness (two homozygous where 1 is dominant and the other is recessive) and (two heterozygous with normal hearing dominant over deafness recessive)
Explanation:
The parents are of genotype heterozygous dominant and homozygous recessive. Supposing the dominant allele is N and the recessive allele is n, one of the parents will be Nn while the other nn. The phenotypic (based on visible characteristics) ratio will be 1:1 for dom/rec and rec/rec as indicated in the diagram below.
Answer:
The First and Third one for sure
Explanation:
Carnivores eat primary consumers as well as other carnivores if I'm not wrong, which would make them secondary or higher consumers.
Also, herbivores eat producers, which are plants and stuff and basically organisms that make their own food, which would make them primary consumers.
Rough and smooth ER is the two kinds
