Protein synthesis in the ribosomes
Can you list your description options and I’ll help you from there?
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
Answer:
Some species are similar in structure because they are evolved from the same ancestors while some differences are also present in them due to the changes occurs in the body because of adaptation to environmental conditions.
Grizzly bears and sea otters have canine teeth because canine teeth are used to crushing hard food materials such as fishes and shells.
Explanation:
Canine teeth are present in the grizzly bear and sea otters due to eating of food materials which are hard. Canine teeth used to crush the food materials.
