The Punnett square predicts a 9:3:3:1 ratio for phenotype. Explain what the ratio means.
Aleksandr-060686 [28]
This occurs in dihybrid crosses
There is a 9/16 chance of the offspring have all dominant traits
A 3/16 chance of the offsprings traits being dom/rec or rec/dom
A 1/16 chance of the traits being all recessive.

For example if Tall is dominant to short and Red is dominant to green
9/16ths of the offspring will be Tall and Red
3/16ths will be either Tall and green OR short and Red
1/16ths chance the offspring will be short and green

amid [387]

Answer:

The correct answer is - option C.

Explanation:

Glutamate dehydrogenase is also known as GDH which present in most of the microorganisms or the mitochondria of eukaryotic organisms. It is the only enzyme that can use both NAD+ and NADP+.

Glutamate dehydrogenase is inhibited by the GTP or ATP. One of the main causes of the catabolism amino acid is metabolites for gluconeogenesis. If the gluconeogenesis is likely to be active due to the result of when glutamate dehydrogenase is active.

Thus, the correct answer is - option C.

Fertilization takes place when a sperm joins a(n)
melamori03 [73]
Q1. The answer is egg.

The fertilisation is a fusion of two gamete cells which results in the formation of the zygote. Sperms and eggs are gamete cells, male and female, respectively. After a sperm and an egg fuse, i.e. the fertilisation takes place, a zygote is created and then begins a development of an embryo.


Q31. The answer is 100% chance

Alleles:
T - the dominant allele for the tongue rolling
t - the recessive allele

Genotypes and phenotypes:
TT - people able to roll tongue 
Tt - people able to roll tongue
tt - people not able to roll tongue

<span>The mother’s genotype is TT and the father’s genotype is TT. The offspring will get T allele from the mother and T allele from the father:
Parents:            TT        x         TT
Offspring:     TT      TT      TT         TT

So, all of the offspring will have genotype TT and will be able to roll their tongues.
 

Q32. The answer is codominant.

A codominance is a pattern of inheritance in which both alleles of a gene are expressed. So, there are no dominant and recessive alleles and both will affect the phenotype. For example, plants with alleles for both red and white flowers will have flowers that are both red and white.</span>
