Answer:

Expected outcome: HH, Hh, Hh, and hh

The phenotypic ratio of the offsprings will be 3 hairy stems : 1 hairless stem

Explanation:

This question involves a single gene coding for possession of hair on stems or not in tomato plants. The allele for hairy stem (H) is dominant over the allele for a hairless stem (h).

According to this question, if two tomato plants that are heterozygous for hairy stems (Hh) are crossed, the following gametes will be produced by each parent: H and h. Using these gametes in a punnet square, the following proportion of offsprings will be produced:

HH, Hh, Hh, and hh

3 hairy stems (HH, Hh, Hh) : 1 hairless stem (hh).

When a skeletal muscle relaxes, what causes the myosin cross-bridges to separate and the thin filaments to return to their origi
Rina8888 [55]

When a skeletal muscle relaxes,myosin head attach to actin by breaking down ATP to ADP and phosphate with the help of myosin ATPase. The myosin head forms the cross -bridges on the active site of the actin.The cross-bridge pulls the actin which slide over the myosin. The release of ADP completes the cross-bridge movements . ATP attaches to myosin, and break the actin -myosin cross-bridge. Thus breaking of ATP into ADP and phosphate help the thin filament to return to their original position.

The mammals whose offspring are little more than embryos are? A. Monotremes B. Marsupials C. Placentals
saveliy_v [14]
The answer is "B. Marsupials". Marsupials undergo relatively premature births compared to many other species, and although this puts the baby at risk, it lessens the risks for the mother.

klasskru [66]

Answer:

Explanation:

If the disorder is recessive, neither parent has to have the disorder because

they can be heterozygous. The characteristic features of autosomal recessive inheritance is as follows:-

•Appears in both sexes with equal frequency

• Trait tend to skip generations

• Affected offspring are usually born to unaffected parents

• When both parents are heterozygous approx. 1/4 of the progeny will be affected

• Appears more frequently among the children of consanguineous marriages.

The given pedigree follows these features. So the correct option is 'Autosomal recessive trait'.

Please correct me If I am wrong :)
