Answer: One parent is IAi and the other parent is IBi
Explanation: As this trait is codominant, the child can inherited IA, IB or i.
Tina has type O, which means she is ii and her sister is AB, so her genotype is IAIB. Now, to have a child with a recessive trait both parents has to carry at least one allele for the recessive, i. Rosa is type AB which means she had to have inherited one allele IA from one of her parents and the other IB from the other parent. Thus, one parent is IAi and the other is IBi.
Answer:
Option A
Explanation:
Only an autotrophic species can convert methane into food.
Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.
Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.
Hence these autotrophic bacteria’s will be considered as producers as they produce food.
Thus, option A is correct.
Couples who cohabit are characterized by a lower level of commitment when
compared to married couples. Cohabiting couples are two people who live
together but are not married. The form of relationship between the two people
is a loose relationship because it does not have a legal binding and they are
free to separate at any time.
The subunits are called nucleotides
