A couple plans to have a child. the mother is homozygous for an autosomal recessive mutation. the father is heterozygous for the

adoni [48]

Answer:

The possible genotypes of the children are Hh and hh.
The probability of genotype Hh = 1/2
The probability of genotype hh = 1/2

Explanation:

Autosomal genes are the genes present on any of the chromosomes except the sex chromosomes.

An autosomal recessive mutation is the mutation in an autosomal gene which only expresses itself in the phenotype in homozygous condition and affects both males and female equally.

For the given question, let the autosomal gene be represented by H (dominant) and h (recessive)

According to the question,

Since the mother is homozygous her genotype would be hh and the father is heterozygous so his genotype would be Hh.

The following cross is made to know the genotypes of the children :

hh X Hh--------> Hh Hh hh hh

So the possible genotypes of the children are Hh and hh as shown in the cross.

Note : An image is attached representing the cross in a Punnett square.

The probability of an event = No. of favourable outcomes/total no. of outcomes

The probability of occurrence of genotype Hh would be = 2/4 = 1/2

Similarly, the probability of occurrence of genotype hh would be 2/4 = 1/2

How do the products of glycolysis and krebs cycle relate to the electron transport chain?

Snezhnost [94]

During the process of glycolysis and krebs cycle (which is also known as tricarboxylic acid (TCA) cycle or citric acid cycle), there is breakdown of large molecules to product smaller molecules and energy including ATP.

So the answer to this would be:

Glycolysis and Krebs cycle produce the molecules that shuttle electrons to the electron transport chain

Which type of rna carries a genetic code from dna to the ribosome? a.mrnab)qrnac)rrnad)trna

Serjik [45]

They type of RNA that does this is mRNA, messenger RNA, hence the name, it provides the message or particular genetic sequence that has been transcribed from DNA to the ribosome for which the synthesis of the polypeptide can occur.

Describe weight reducing adaptation of birds

Novay_Z [31]

Answer:

Birds have a significant number of reduced muscles to help them reduce their weight. The most-developed muscles in birds are the flight muscles that they need to fly. The bones are mostly fused, reducing the need for muscles to hold the bones together. The skulls of birds are very thin and the beaks are very light.
