Answer:
561
Explanation:
This is math so I got you.
This is just going to subtract 12 from 55 since we don't now when during her 12th year of age she started or when during her 55th year f age she ended.
55 - 12 = 43, so about 43 years. Also not going to account for leap years. So we are just going to say each year had 365 days. so 43 years and 365 days per year = 15695 days.
If her cycles were each about 28 days we divide the total number of days by 28 and that tells us about how many cycles there were.
15,695 / 28 = 560.5 which I will round to 561
561 cycles means 561 eggs if my biology knowledge is as accurate as I think it is.
Answer:
The question lacks options, the options are:
A) 1 out of 16
B) 3 out of 16
C) 6 out of 16
D) 9 out of 16
The answer is 1 out of 16
Explanation:
This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.
When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.
9 represents offsprings that are dominant for both traits
The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.
1 represents offsprings that are homozygous recessive for both traits.
Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.
Answer:
Cas9
Explanation:
Genome editing techniques have been developed to exploit the CRISPR system of bacteria and archaea. Only the Cas9 component of the system is used in editing.
Ggbb = gray hair and red eyes
ggBB = white hair and black eyes
GgBb = gray hair and Black eyes
ggbb = white hair and red eyes
