Answer:
A. VG = 80
B. Broad sense heritability = 0.80
C. Narrow sense heritability = 0.30
D. Average yield = 430 Units
Explanation:
A. Given that
VA = 30
VD = 50
VI = assumed not available
Therefore
Total genetic variance (VG) = VA + VD
= 30 + 50
= 80
VG = 80
B. Given that
VP = 100
VG = 80
Broad sense heritability, H2 = VG/VP
= 80/100
= 0.80
C. Given that
VA = 30
VP = 100
Narrow sense heritability, h2 = VA/VP
=30/100
= 0.30
D. The difference in selection = 500 - 400
= 100
Recall,
Selection response is heritability multiplied by selection differential.
That is
R = h2S
Selection differential = 100
Heritability h2 = 0.30
Selection response = 0.30 × 100
= 30units
Therefore, expected average yield = 400 + 30
= 430 Units
The baby is considered as extremely preterm infant.
The babies that are born alive before the completion of a period of 37 weeks of pregnancy are the preterm babies. There are three categories into which preterm born babies are distinguished: moderate to late preterm for 32-37 weeks, very preterm for 28-32 weeks and extremely preterm for less than 28 weeks.
Premature births are one of the major causes of death of children under the age of 5 years. The babies that survive may have problems and may be visual or hearing impaired, may have learning disabilities etc.
If mitosis occurs correctly, the division of one cell by mitosis produces two cells.
Reading background information because it gives ideas from the author himself.
It is chloroplast I guess because once i read that mitochondria has not much importance in being an autonomous organelle
