Answer:
Ben - Y Xc
Jen - XCXC
Violet - XCXc
Seraphina - XCXc
Samuel- Y Xc
Explanation:
Given -
Ben has a cleft chin
Let the allele for cleft chin be "c"
and the allele for normal chin be "C"
When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.
This means that the allele C could be X -linked and the mother is not the carrier but the father is
The genotype of father Ben would be Y Xc
Genotype of mother would be XCXC
Genotype of two daughters XCXc , XCXc which means they are carrier for the next generation
Genotype of Boy - Y Xc
Answer:
The correct answer will be option- permits complementary base pairing
Explanation:
DNA contains four types of nitrogenous bases which pair with one another, identified by Erwin Chargaff.
Chargaff suggested that adenine binds thymine forming two hydrogen bonds and cytosine binds guanine forming three hydrogen bonds.
This base pairing between the complementary groups is known as a complementary base pairing which plays an important role in DNA.
The complementary base pairing allows the formation of the helical structure of DNA, the base pairs to be arranged in most energetically and favourable way and replication and transcription processes.
Thus, permits complementary base pairing is the correct answer.
Answer:
Brachydactyly and Huntington are phenotypic diseases that develop when a person has one or two dominant alleles for these traits.
John's father has the Huntington disease, but not brachydactyly so his genotype is Hh/bb.
John's mother is a healthy women with brachydactyly, so her's genotype is probably hh/BB or hh/Bb.
Answer:
The cow uses all but stores ten percent of what they eat.
Explanation:
For example, a plant produces 100 percent energy. The plant needs to use the energy for survival.
When a cow eats the plant, it only gains 10 percent of the energy.
Then, say a wolf eats the cow.
The wolf only gets 1 percent of the energy that is produced by the plant.
It was affected by natural selection.
If this is wrong someone please tell me.
